Smith-Blair 411 Steel Coupling
Smith-Blair Pipe 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.
Smith-Blair water couplings consists 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
