Plug PP 1½" Male Thread 10 bar Black - 0121245

Plug PP 1½” Male Thread 10 bar Black

Rated to a working pressure of 10 bar at 20 °C, this 1½” male-threaded polypropylene plug is designed to seal open female BSP-threaded ports on pool pipework, filter housings, pump bodies, and chemical-dosing manifolds. Its solid PP construction makes it equally suitable for temporary commissioning blanks and permanent closures in both fresh and salt-water systems.

Material & chemical resistance

Moulded from polypropylene, the plug resists chlorine, salt, most pool chemicals, and common disinfectants without corroding or degrading over time — an advantage over brass or galvanised-steel alternatives in permanently wet plant-room environments. The black pigmentation is UV-stable, so the fitting retains its integrity even when installed in exposed outdoor manifolds.

Thread fit & pressure rating

The 1½” BSP male thread engages directly into any standard female BSP socket, tee, or valve body of the same size — no adaptor required. At 10 bar PN rating, it comfortably exceeds the operating pressures of typical domestic and light-commercial pool circulation systems, giving installers confidence across a wide range of filter and pump configurations.

Typical pool applications

Commonly used to blank unused ports on multiport valves, filter heads, and chemical injection points, or to cap pipework temporarily during phased installation. The 1½” size suits the majority of standard pool circulation plumbing, covering pools from modest residential pools up to larger commercial installations with matching BSP pipework.
