Service Saddles
& Tapping Saddles
The leak-free tapping boss for every new water service connection. Bolted onto a live distribution main, a service saddle lets you tap a new corporation stop or service line without shutting the system down. Thirteen styles — ductile iron, bronze, and all-stainless — covering 1" through 42" pipe and 5/8" through 4" taps in both NPT and CC thread. Same-day quote response from Houston stock.

What a Service Saddle Is
The Foundation of Every Service Connection
A service saddle (also called a tapping saddle) clamps around a water main and provides a reinforced, gasketed outlet boss through which the main can be drilled and tapped — under pressure, without interrupting service — to start a new service line.
When a utility needs to connect a new customer, fire line, or branch to an existing distribution main, it does not cut the main. Instead, a service saddle is bolted around the pipe, a corporation stop (or tapping valve) is threaded into the saddle outlet, and a tapping machine drills through the corp stop and the pipe wall while the line stays pressurized. The saddle’s gasket seals the connection; its body gives the corporation stop enough thread engagement to hold against system pressure and the torque of the tapping drill.
Correct saddle selection is non-negotiable. A saddle that does not match the pipe outside diameter (OD), the pipe material, and the tap size and thread will leak, damage the tap drill, or fail at pressure. The three pieces of information that determine the right saddle every time are: actual pipe OD, pipe material, and the tap size + thread type (NPT or CC).

Which Service Saddle Do You Need?
The styles look similar but differ by pipe material, strap configuration, body metal, and pipe diameter. Match your situation below to narrow to the right style, then confirm OD and tap thread.
Standard residential / commercial tap on DI or steel
Single-strap configuration for typical service connections. Galvanized bale for normal soils; stainless strap where corrosion resistance is required.
→ Style 311 (galv) or 315 (SS strap)
Larger main (8"+) or higher clamping force needed
Double-bale or double-strap for greater circumferential grip and sealing on bigger pipe and irregular surfaces. Often spec-required on mains 8" and up.
→ Style 313 (double bale) or 317 (double strap)
PVC pipe (C-900 / C-905)
PVC needs even load distribution on a softer wall. Use a DI body with a double-wide stainless strap, or a bronze saddle sized to PVC OD.
→ Style 397 (PVC) or 325 (bronze)
Copper service tubing / all-bronze wetted spec
Bronze body for galvanic compatibility with copper tubing and brass corporation stops, or where the utility mandates all-bronze wetted surfaces.
→ Style 325 Bronze
Corrosive environment — full stainless required
Offshore, desalination, salt-marsh soils, or long-term asset programs. All-304 stainless construction from strap to boss.
→ Style 371 (single stud) or 372 (double stud)
Large tap (3" or 4") for fire line or big branch
A standard 5/8"–2" saddle cannot carry a large-diameter tap. The 357 provides a 3" or 4" NPT tapping boss.
→ Style 357 Large Tap
Concrete cylinder pipe (CCP)
Standard DI saddles cannot seal against a concrete OD. Epoxy-coated body and straps resist the alkaline concrete surface.
→ Style 362 Concrete Pipe
Large-diameter transmission main (18"–42")
Strap geometry built for big mains, with epoxy-coated straps for long-term buried service.
→ Style 366 Large Diameter
Mixed-vintage pipe / want fewer SKUs to stock
A single wide-range part number spans a broader OD band, simplifying inventory across mixed pipe systems. All stainless.
→ Style 377 Wide Range
New tap next to a pipe defect
Repair service saddle: establishes a new service outlet while sealing a nearby crack, pulled tap, or stripped thread in one device.
→ Style 331 Repair Saddle

Key Terms Explained
Service saddle datasheets assume waterworks fluency. Here is what each term means so you can read a spec sheet and order right the first time.
Most Important
Tap Thread
NPT vs CC — the #1 ordering error
- NPT threadTapered; for gate/ball valves & threaded fittings
- CC threadAWWA taper; for corporation stops
- Also calledCC = Mueller / AWWA / corp cock thread
- Wrong threadWon’t seal or damages the corp stop
- Most commonCC for service taps in North America
Strap Configuration
Bale vs Strap
How the saddle clamps the pipe
- BaleU-bolt style band over the pipe
- StrapFlat band wrapping the pipe OD
- SingleOne band — standard service taps
- DoubleTwo bands — more grip on larger/rough pipe
- Double-wideSpreads load — used on softer PVC wall

Critical Distinction
CC Thread vs NPT Thread
Every Smith-Blair saddle outlet is offered in two thread types. Choosing the wrong one is the single most common service-saddle ordering mistake — and it cannot be corrected in the field.
NPT — National Pipe Thread (Tapered)
•
What it is
The general-purpose tapered pipe thread used across plumbing and industrial fittings.
•
Mates with
Gate valves, ball valves, brass nipples, threaded adapters — standard NPT-threaded fittings.
•
Use when
The tap connects to a valve or fitting with NPT threads, or for large 3"/4" taps (Style 357).
CC — Corporation Cock Thread (AWWA Taper)
•
What it is
The waterworks-specific tapered thread standard — also called AWWA/CC taper or Mueller thread.
•
Mates with
Corporation stops from Mueller, Ford, and A.Y. McDonald — the most common service tap fitting in North America.
•
Use when
Starting a standard residential or commercial service connection with a corporation stop. This is the default for most utilities.
⚠ NPT and CC Are Not Interchangeable
CC and NPT taper angles and pitch differ. An NPT corporation stop threaded into a CC saddle (or vice-versa) will either fail to seal under pressure or strip and damage the corporation stop. Always confirm the corporation stop’s inlet thread and order the matching saddle outlet. When in doubt, CC is the most common service-tap thread.
Standard Configurations
Single & Double Bale / Strap Saddles
Strap count drives clamping force. Single-strap saddles handle the majority of standard service taps; double-strap and double-bale saddles add grip and sealing for larger or higher-pressure mains and irregular pipe surfaces.
Style 311 & 315 — Single Bale / Single Strap, Ductile Iron
The most widely used configuration for standard residential and commercial connections. A rigid ductile iron body (ASTM A536) gives the corporation stop enough thread engagement to withstand tapping torque and system pressure. The two styles share the same DI body and differ only in the clamping band.
- Style 311 — single bale, electro-galvanized carbon steel bale. Cost-effective for typical soils. 1"–12" nominal, 5/8" CC through 2" NPT taps.
- Style 315 — single strap, 304 stainless steel strap replaces the galvanized bale for aggressive soils or where utility specs require stainless. Same DI body. 1"–12" nominal.

Style 313 & 317 — Double Bale / Double Strap, Ductile Iron
Two clamping bands provide greater circumferential force and better sealing on larger diameters, higher-pressure systems, and pipe with irregular or deteriorated surfaces. Many utility specs require double-strap or double-bale saddles for taps on mains 8" and larger.
- Style 313 — double bale, DI body, available with Epoxy-Coated, 304 Stainless, or Galvanized bales to match the environment. Covers small through large taps; large-diameter ranges to 24"+.
- Style 317 — double strap, DI body, dual 304 stainless straps for maximum corrosion resistance and grip. 4"–24" nominal; 5/8" CC through 4" NPT taps. Preferred in coastal and industrial systems.

Body Material Selection
Bronze & All-Stainless Saddles
Beyond ductile iron, two premium body materials solve specific corrosion and compatibility requirements.
Style 325 — Bronze Service Saddle
Bronze body saddles are specified where galvanic compatibility with copper service tubing and brass corporation stops is required, or where the utility’s material standard mandates all-metallic / all-bronze wetted surfaces. A premium product for high-value residential developments and copper service systems. Sized to fit PVC pipe at steel or ductile-iron OD.
- Single 304 SS strap — extra-wide stainless strap for 3/4"–2" taps on smaller mains.
- Double 304 SS straps — dual straps for larger mains; extra-wide body increases seating area for improved gasket compression.

Specialty & Application-Specific
Specialty Service Saddles
The specialty series covers non-standard tapping conditions found in aging or complex distribution systems.
Repair + Tap
Style 331 — Repair Service Saddle
Double bale, epoxy-coated DI body. Establishes a new service outlet while sealing a nearby defect — pulled-out or broken direct taps, stripped threads, or cracked pipe. 4"–12"; 5/8" CC through 2" NPT.
Large Tap
Style 357 — Large Tap (3" & 4" NPT)
DI body with stainless straps, engineered for large-diameter service and fire-protection taps that standard 5/8"–2" saddles can’t carry. 6"–12" pipe. NPT only. Not for ductile iron pipe.
Concrete Pipe
Style 362 — Concrete Cylinder Pipe
DI body with epoxy-coated straps for concrete cylinder pipe (CCP), where standard DI saddles can’t seal against the concrete OD. Epoxy resists the alkaline surface. 12"–36" nominal.
Large Diameter
Style 366 — Large Diameter
DI body, epoxy-coated straps, for transmission mains 18"–42" where standard strap geometry is insufficient. Long-term corrosion protection in buried service. Taps to 2-1/2".
Wide Range
Style 377 — Wide Range, All Stainless
All 304 stainless with wide-range OD accommodation — one part number covers a broader span of pipe ODs, simplifying inventory for utilities with mixed-vintage pipe. 4"–12".
PVC Pipe
Style 397 — PVC Pipe
DI body with double-wide 304 stainless strap, engineered for steel- and DI-sized PVC where C-900 / C-905 ODs differ from DI. The double-wide strap distributes load evenly on the softer PVC wall. 2"–12".
Also Stocked — Style 281 Full Circle Repair Clamp
For pure pipe repair (no service tap), the Style 281 full-circle wide-range repair clamp seals splits, cracks, and pinholes on 3"–12" pipe in gasket widths from 7.5" to 30". 304 stainless, conforms to AWWA C223. It is a repair clamp, not a tapping saddle — ask us if you need repair coverage rather than a new tap.

Approvals & Materials
Potable Water Certification & Why Material Matters
Service saddles touch the drinking-water stream, so material safety and corrosion behavior both matter. Here is what is certified and why each body metal exists.
✓ Certified for Potable Water
Smith-Blair service saddle gaskets are Nitrile (Buna-N) certified to NSF/ANSI 61, the standard governing materials in contact with drinking water. All saddle styles in this collection conform to AWWA C800 for service-line threads and fittings; the Style 281 repair clamp conforms to AWWA C223. For project submittals or NSF 61 documentation on a specific style, contact us and we will coordinate with Smith-Blair’s technical team.
Why Different Body Materials Exist
Body metal is a corrosion and compatibility decision, not just a price one. The wrong metal in the wrong environment fails early — galvanic corrosion, soil attack, or alkaline degradation.

Ordering Reference
How to Read a Smith-Blair Saddle Catalog Number
Every saddle part number encodes the style, the pipe OD, and the tap size + thread. Understanding the structure makes ordering and cross-checking fast.
Catalog Number Structure
372 - 00 1110 14 - 000
372 = style | 1110 = pipe OD ×100 (11.10") | 14 = tap code (2" NPT) | 000 = configuration suffix. So 372-00111014-000 = Style 372, 11.10" OD, 2" NPT tap, standard config.
Tap Code Reference (the 2 digits before the suffix)
| Code | Tap Size & Thread | Code | Tap Size & Thread | Code | Tap Size & Thread |
|---|---|---|---|---|---|
| 04 | 1/2" CC | 09 | 1" CC | 14 | 2" NPT |
| 05 | 5/8" CC | 10 | 1-1/4" NPT | 15 | 2" CC |
| 06 | 3/4" NPT | 11 | 1-1/4" CC | 16 | 2-1/2" NPT |
| 07 | 3/4" CC | 12 | 1-1/2" NPT | 17 | 3" NPT |
| 08 | 1" NPT | 13 | 1-1/2" CC | 18 | 4" NPT |
Note the NPT / CC pairing: odd vs even codes within each tap size denote thread type (e.g., 14 = 2" NPT, 15 = 2" CC). Configuration suffixes vary by style (e.g., double-strap and stainless-bale lines). Always verify the final catalog number against actual pipe OD — call 281.664.8000 with pipe OD, material, tap size, and thread for confirmation.
Technical FAQ
Common Questions
What is a service saddle used for?
It provides a sealed, reinforced outlet on a water main so a new service line can be tapped — under pressure, without shutting the system down. A corporation stop threads into the saddle outlet and a tapping machine drills through it into the pipe.
Do I order CC or NPT thread?
Match the inlet thread of the corporation stop or fitting you are connecting. CC (corporation cock) is the most common for standard service taps and pairs with Mueller, Ford, and A.Y. McDonald corp stops. NPT is for standard valves and threaded fittings. The wrong thread won’t seal or will damage the corp stop — and it can’t be fixed in the field.
How do I know which size to order?
Order by actual pipe OD, not nominal size. A 6" ductile iron pipe is 6.90" OD; 6" PVC C-900 is 6.63". Measure with a caliper or check the mill certificate, and tell us the pipe material so we match the correct OD range.
Single strap or double strap?
Single strap/bale (311, 315) handles standard service taps. Double strap/bale (313, 317) adds clamping force and sealing for larger mains, higher pressure, and irregular or deteriorated pipe surfaces — and is often spec-required on mains 8" and larger.
Why are there different body materials?
Corrosion and compatibility. Ductile iron is the strong, standard choice. 304 stainless straps or all-stainless bodies (315, 317, 371, 372, 377) resist aggressive soils and coastal/industrial exposure. Bronze (325) is galvanically compatible with copper tubing and brass corp stops. Epoxy-coated bodies/straps (313, 362, 366) protect against buried and alkaline (concrete) environments.
Are Smith-Blair saddles safe for potable water?
Yes. The Nitrile (Buna-N) gaskets are certified to NSF/ANSI 61 for drinking-water contact, and the saddles conform to AWWA C800. We can provide NSF 61 documentation and submittals on request.
Which saddle goes on PVC pipe?
Style 397 is the PVC-specific saddle — a ductile iron body with a double-wide stainless strap that distributes load evenly on the softer PVC wall, sized for C-900/C-905 OD. Style 325 bronze is also used on PVC in copper/bronze systems. Always confirm the actual PVC OD before ordering.
Can I tap a 3" or 4" service?
Yes — use Style 357, engineered for 3" and 4" NPT taps on 6"–12" steel or PVC pipe (not for ductile iron pipe). Standard 5/8"–2" saddles cannot carry a tap that large.
Need a Saddle Sized or Quoted?
Send us pipe material, actual pipe OD, nominal pipe size, tap size, and thread type (NPT or CC). We confirm the catalog number and stock-check in minutes.
