The Plasson Blanking Plug 7129 (32mm) is a precision-molded internal blanking component designed to convert a standard 32mm Plasson compression socket into a permanently or temporarily capped off port. It is widely utilized by plumbing, utility, and agricultural professionals during system modifications, testing procedures, or phased construction to block an unused fitting outlet without altering the main pipeline setup.
 
Manufactured from high-grade virgin polypropylene, this blanking plug provides exceptional impact strength, environmental stress resistance, and complete immunity to rust or electrochemical corrosion. Unlike end caps that fit directly over a raw pipe, the 7129 plug is inserted into the compression socket of an existing fitting in place of the pipe, engaging with the fitting’s internal captive O-ring and split ring mechanism to form a reliable pressure-tight seal upon tightening the nut.
 
Engineered for quick, tool-free installation on site, the plug allows technicians to isolate specific branches or convert tees and elbows into temporary line terminations effortlessly. Fully WRAS-approved for wholesome potable water supply and rated for high working pressures up to 16 bar (PN16), this trade-quality blanking plug delivers dependable, long-term sealing performance across subterranean and above-ground infrastructure.
