NAPCO’s C900/RJ Certa-Lok® PVC Pressure Pipe is manufactured to meet the standards of today’s municipal needs for water and wastewater pressure applications. This unique coupled, restrained joint system is jobsite proven for decades and designed for trenchless applications with robust tensile strength for pulling multiple segments underground. The low profile coupling allows for quick and easy assembly without interrupting the pulling process and provides greater deflection at the joint for leak-free results. The system assembles in minutes and eliminates costly time consuming fusion.
