Product Description

Groove Lock fittings are a type of mechanically joined grooved pipe coupling. Unlike standard grooved couplings that use bolts to connect, Groove Lock couplings use a spring-loaded locking mechanism within the fitting body itself.

The locking mechanism provides a unique freewheeling feature that allows the pipes to move independently within the joint coupling up to 5 degrees of angular deflection and 1/4 inches of lateral movement. This accommodates potential movement and vibration in the pipeline.

Some key advantages of Groove Lock fittings include:

  • They can be installed quicker than bolted couplings as no tightening of bolts is required. This saves installation time.
  • The freewheeling motion absorbs thermal expansion/contraction and seismic activity without stressing the pipe.
  • Locked connections are resistant to over-tightening issues that can occur with bolts.
  • The seal is automatically maintained even if movement causes the connection to loosen over time.
  • Disassembly is simpler as fittings unlock inward with hand pressure for maintenance access.
