Smith-Blair Replacement Parts for OMNI Couplings, Caps and FCAs
Gaskets, follower flanges, center sleeves, end cap bodies, 912 FCA bodies and the bolts, nuts and washers that hold them together. Every part carries its Smith-Blair part number, so you can match the one in your hand and keep a coupling, cap or adapter in service.

NSF/ANSI 61-GNitrile gaskets
The Smith-Blair OMNI system is built from interchangeable parts: one center sleeve per nominal size, a follower flange and a gasket on each end that set the pipe OD, and track-head bolts that draw the followers in. The Style 441 cast coupling, 442 long-sleeve coupling, 482 end cap and 912 flanged coupling adapter share the same gaskets and follower system. When one part is damaged or a pipe OD changes, you replace that part, not the whole fitting.
Send the part number from the old part, or the coupling style and measured pipe OD, and we confirm the replacement the same day. Call 1-888.510.4036 or email sales@watermainsupply.com. Genuine Smith-Blair equipment, factory-new in original packaging — sold and supported by Watermain Supply, an independent industrial supplier.

Identify Your Part
OMNI gaskets and followers are permanently marked with a part number and OD range.
| Part | What to look for | How to order |
|---|---|---|
| Gasket | Part number ending -069 and an OD range molded on the gasket | Match the part number, or the measured pipe OD |
| Follower flange | Part number ending -045 cast in; color shows pipe type: red IPS, blue ductile, gray AC | Match the part number and color, or the pipe OD and type |
| Center sleeve | Nominal size; 441 standard length or 442 7 in or 12 in | Nominal size and style; reducing sleeves by both sizes |
| 482 end cap body | Part number ending -245 | Nominal size |
| 912 body and O-ring | One body per nominal size, ANSI 125/150 drilling | Nominal size; follower by pipe OD |
| Bolts and nuts | Diameter, length, neck shape (oval or square) and finish | Size and finish: alloy, electro-galvanized or 304 stainless |
How to measure: clean the pipe where the gasket seats, wrap a pi tape around the bare pipe and take two readings 90° apart. Order by that OD, not the nominal size: a 6 in pipe can be 6.63 in (steel, IPS PVC), 6.90 in (ductile iron, C900 PVC) or larger on old cast iron.
Bolt Counts by Size
From the Smith-Blair 441 and 442 selection charts. One 5/8 in heavy hex nut per bolt.

912 FCA: four cross bolts and four flange bolts or studs on 3–8 in (plus four tee bolts on 4–8 in), six of each on 10–12 in. Three nuts per stud and one per flange bolt. Bolt length depends on the pipe OD within a size: check the selection chart on the 441, 442 or 912 datasheet before ordering.
Parts or a New Fitting?
We tell you which is cheaper before you order.
Buy the Part
- 4 in and larger: one gasket and follower costs about half a new coupling or less.
- Changing a coupling end to a different pipe OD.
- Corroded hardware on a sound sleeve, cap or FCA body.
Buy a New Fitting
- 2 and 2-1/2 in: a complete Style 441 often costs about the same as a gasket and follower.
- More than one end damaged, or the sleeve is cracked.
- A complete 482 end cap or 912 FCA when the body is damaged.
Frequently Asked Questions
Are these genuine Smith-Blair parts?
Yes. Every part is factory-new Smith-Blair equipment with its Smith-Blair part number, sold and supported by Watermain Supply, an independent industrial supplier.
How do I find the right gasket or follower?
Measure the pipe OD with a pi tape and pick the OD range, or read the part number and range molded on the old gasket or cast on the follower. Email the number or a photo and we confirm the part.
Do the same gaskets fit the 441, 442, 482 and 912?
Yes. They all use the OMNI gasket system. The 482 end cap takes the largest gasket within its nominal size.
What do the follower colors mean?
Smith-Blair color-codes followers by pipe type: red for iron pipe size OD, blue for ductile iron OD, gray for asbestos cement OD.
Why are some parts sold in packs?
Small bolts, nuts and washers are sold in packs of 2 to 50 so each line is worth shipping. The pack size shows in the part number option.
Should I buy parts or a complete coupling?
On 2 and 2-1/2 in, a complete 441 coupling often costs about the same as a gasket and follower, so a new coupling is usually the better buy. From 4 in up, replacing one end costs about half a new coupling or less.
How many bolts does a 441 take?
Two 5/8 in bolts on 2 and 2-1/2 in, four on 3 to 6 in, six on 8 and 10 in, eight on 12 and 14 in and ten on 16 in, with one heavy hex nut per bolt per the Smith-Blair selection chart.
Are spare parts returnable?
No. Smith-Blair parts are made to order and non-returnable, so we confirm the part number before the order ships.
What is the warranty?
One year from the date of shipment by Smith-Blair, against defects in materials and workmanship, under Smith-Blair published warranty.
Need a Smith-Blair Part Matched?
Send the part number, a photo of the part marking, or the coupling style and measured pipe OD. We reply the same day with the part number, price and ship date.
Technical data on this page is taken from Smith-Blair product literature and the Smith-Blair 2025 price book and is subject to change by the manufacturer.
