The Certa-Lok joint system enables a non corrosive restrained joint system that utilizes precision machined grooves on the pipe and inside the couplings. This system allows for a spline to be inserted locking the pipe and coupling together. A flexible elastomeric O-ring provides a hydraulic seal.

This system enables fast assembly. It also provides the user disassembly, allowing for system changes or portability. The Certa-Lok joint can be used in above and below ground applications.
