The Plasson Compression End Plug 7120 (20mm) is a robust, permanent or temporary terminating fitting designed to seal off the end of a 20mm metric MDPE (Medium Density Polyethylene) water supply pipe line. It is widely utilized by plumbing, utility, and agricultural professionals to cap open pipe ends during system flushing, pressure testing, phase-by-phase network construction, or final line terminations.
 
Manufactured from high-grade virgin polypropylene, this end plug provides exceptional impact strength, environmental stress resistance, and complete immunity to rust or corrosion. The internal mechanism features a captive O-ring seal and a high-tensile split ring that firmly grips the exterior of the 20mm pipe as the nut is tightened, providing superior resistance to hydraulic thrust and preventing pipe blow-out under system pressure.
 
Engineered for quick, tool-free installation on site, the fitting simply pushes onto the cut pipe end and tightens by hand or standard wrench to create an instant, reliable seal. Fully WRAS-approved for wholesome potable water supply and rated for high working pressures up to 16 bar (PN16), this trade-quality compression blanking plug ensures dependable, long-term performance in both above-ground and direct-burial applications.
