Smith-Blair Steel Couplings offer many distinct advantages when installed in a piping system. Properly selected and installed flexible couplings maintain the continuity of the pipe system, retain the line contents under internal pressure and prevent infiltration under vacuum. Our couplings consist of one cylindrical sleeve with conical inner surfaces at each end; two resilient, wedge-shaped, specially-compounded rubber gaskets; two ring-shaped followers and a set of high-strength, low-alloy track-head, oval-neck, rolled-thread bolts with heavy hex nuts.

Flanged Coupling Adapters
Smith-Blair Flanged Coupling Adapters (FCA) provide versatility on the job site by eliminating the need for a flanged spool. Our FCAs combine a flexible coupling and flange to create a compact fitting connecting plain-end pipe to flanged fittings, meters, valves or equipment.

Smith-Blair Expansion Joints are carefully designed and manufactured according to specific engineering requirements. Each expansion joint consists of a slip pipe that telescopes within a body to compensate for changes in the length of a pipeline. The body of the expansion joints has a packing chamber containing resilient packing to form a seal between the body and the slip pipe.

EZ-W Restraint Couplings
Smith-Blair EZ-W Restraint Couplings for water service are designed with push on gaskets and engineered to simplify installation, restrain the pipe joint and ensure a tight seal. EZ-W Couplings can be used to connect IPS PE to steel pipes 1" through 12" diameters and ductile iron to IPS PE, PVC or steel pipe, 2"-8".
