AquaSpring® AWWA C900 Certa-Lok® RJIB PVC Pipe

Westlake Pipe & Fittings’ AquaSpring™ AWWA C900 Certa-Lok® RJIB PVC Pipe is a patented, segmented Restrained Joint Integral Bell (RJIB) C900 pipe system that utilizes a corrosion-proof spline aligned with precision-machined grooves to create a bi-directionally restrained joint that can be assembled in minutes. 

  • Designed for trenchless applications with robust tensile strength for pulling multiple segments underground
  • Helps decrease jobsite footprint and minimize community disruption with a reduced need for job site staging area and traffic control
  • Certa-Lok® provides bi-directional strength that is quick and easy to assemble in any weather conditions
  • Quick and easy assembly without interrupting the pulling process
  • Utilizes Fluid-Tite® gaskets (6" - 24") with superior sealing surface for a leak-free joint and greater deflection capability

What Is Restrained Joint PVC Pipe?

Open Accordion Menu Item

Restrained joint PVC pipe is designed with joints that resist separation under pressure without requiring external thrust blocks. This design provides added security in high-pressure systems, while maintaining the lightweight and corrosion-resistant benefits of PVC.
