The Plasson Compression End Plug 7120 (25mm) is a robust utility fitting designed to permanently or temporarily seal off the open end of a 25mm metric MDPE (Medium Density Polyethylene) water supply pipe. It is widely utilized by plumbing, utility, and agricultural professionals to cap off unused sub-circuits, terminate branch lines, or seal pipeline extensions during system commissioning, pressure testing, or phased installations.
 
Manufactured from high-grade virgin polypropylene with robust internal components, this end plug provides exceptional impact strength, environmental stress resistance, and complete immunity to rust or corrosion. The assembly features a captive O-ring seal and a gripping split ring that locks firmly onto the exterior surface of the pipe when the compression nut is tightened, ensuring absolute structural retention and preventing tube pull-out under operating pressures.
 
Engineered for rapid, tool-free installation on site, the technician simply inserts the prepared pipe end up to the internal stop and tightens the nut by hand or with a standard wrench to achieve an instant seal. Fully WRAS-approved for wholesome potable water and rated for high working pressures up to 16 bar (PN16), this trade-quality compression plug delivers reliable, leak-free performance across demanding subterranean and surface-mounted infrastructure.
