Overview
The Dresser Style 126 Bell-Pack sleeve repairs split cast iron bells and leaking mechanical joints without shutting the line down. Side bolts enclosed in the body compress the side gaskets, and set screws drive an enclosed follower ring to compress the end gaskets for a full circumferential seal.
Application: Permanent repair of cracked bells and leaking joints on cast iron water mains.
- Compact body with maximum inside clearance over the bell
- Rubber-packed Dresser gasket seal
- 1 in vent
- Fusion-bonded epoxy optional
What Ships and What It Needs to Run
Included: the sleeve halves with gaskets, enclosed followers, set screws, side bolts and vent plug.
Pipe prepared before install: clean, round pipe where the gaskets seat, free of gouges and loose scale.
Anchoring, by others: the fitting seals but does not restrain the pipe.
Genuine Dresser equipment, factory-new in original packaging — sold and supported by Watermain Supply, an independent industrial supplier.
12-Month Dresser Warranty
Covered for 12 months from the date of purchase under Dresser’s published warranty terms.
Working Pressure

Installation Notes
- Mark the pipe and stab it into the fitting to the full stab depth.
- Anchor the pipe joint wherever pull-out can occur.
- Read the Dresser installation instructions and warnings before installing.

Before You Order. Anchor the pipe: the sleeve provides a pressure seal only, and Dresser requires the joint to be anchored wherever pipe pullout could occur. Non-stock Dresser parts are not returnable without Dresser’s authorization, and ship time is confirmed when you order. Custom builds (other sizes, widths, gaskets or materials) are available: email
sales@watermainsupply.com with the pipe OD, material and line content.
