Yelomine® ASTM D2241 Certa-Lok® RJ PVC Pressure Pipe

Westlake Pipe & Fittings’ ASTM D2241 RJ Certa-Lok® Yelomine® PVC Pressure Pipe is a segmented, restrained-joint pipe system manufactured from a specially formulated PVC compound that contains impact modifiers and UV inhibitors making it  ideal for aboveground and temporary bypass water and wastewater applications. 

  • Special formulation provides up to 6x the impact strength of normal PVC pipe over an extended period of time
  • Our patented Certa-Lok® joints utilize  precision-machined grooves on the pipe and in both sides of the coupling which, when aligned, allow a spline to be inserted, resulting a bi-directionally restrained joint
  • Flexible elastomeric gaskets in the coupling provide a hydraulic seal
  • Joints assembled with the non-permanent gasket option can be disassembled and reused
