Certa-Lok Yelomine is a restained-joint PVC pressure-piping system with a simple joint design that does not require welding, bolting wrenches or special equipment. The pipe’s joint is formed by precision-matching grooves, which when aligned, allow a spline to be inserted. A flexible O-ring in the coupling then provides the hydrostatic seal. The system can be disassembled later without damaging the pipe and is available in a wide variety of shapes and in versions suited for above- or below-grade applications.
