Certa-Lok® PVC Pipe & Fittings
Westlake Pipe & Fittings’ Certa-Lok® product family leverages our patented spline-lock technology used for trenchless applications and more across the entire PVC pipe & fittings offering. Certa-Lok® utilizes precision-machined grooves on the pipe and within the coupling or integral bell, which—when aligned—allow a nylon spline to be inserted, creating a bi-directionally restrained joint that can be assembled in minutes. Our Certa-Lok® technology is available in pipe & fittings for various market segments and applications.
