Yellowmine pipe is manufactured from a specially formulated PVC compound. The compound contains impact modifiers and ultraviolet inhibitors. 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. A full range of adapters is available to construct virtually any configuration. Elbows, flange adapters, threaded adapters. This piping system is available in 2” to 16” diameters. A proven industrial performer used in applications such as slurry lines, effluent and reclaimed water lines, permanent and temporary potable water lines, Sewer applications, process-piping etc.
