FULL CIRCLE CLAMP COUPLINGS are flexible repair clamps consisting of one or more stainless steel band sections to which cast

Steel 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.

Properly selected and installed flexible couplings maintain the continuity of the piping system, retain the line contents under internal pressure and prevent infiltration under vacuum.

Smith-Blair Pipe Couplings offer many distinct advantages when installed in a piping system.

No special pipe end preparation is required.

Simple installation requires only a wrench.

Pipe does not have to be cut to exact length.

Exact alignment of pipe ends is not necessary.

Coupling fits on outside wall of pipe. No internal projections to disturb flow. No damage to pipe lining.

Many types of pipe including pipes of different materials can be joined.

Every joint is a union. (A length of pipe can be removed by disassembling the coupling.)

Couplings allow for limited expansion and contraction.

Couplings dampen vibration.

Deflection capability of couplings permits installation of curves or changes in grade without the use of special pipe fabrications.

Couplings allow for angular deflection caused by settlement or lateral movement after installation.

Couplings can be installed in any invironment. Weather is not a factor.

No fire hazard due to no welding being required.

Increases the hoop strength of the pipe at the joint.
