NAPCO’s D2241/RJIB CertaLok® Yelomine® PVC Pressure Pipe is manufactured to meet the demands of today’s municipal needs for water and wastewater applications. Certa-lok pipe utilizes precision-machined grooves on the pipe and in the integral bell which, when aligned, allow a spline to be inserted, resulting a fully circumferential restrained joint. A flexible elastomeric gasket in the integral bell provides a hydraulic seal.
We want to help you get your project started. That’s why there are NAPCO representatives all across North America.
