Plug PP 2½" Male Thread 10 bar Black - 7037798

Plug PP 2½” Male Thread 10 bar Black

Rated to 10 bar (PN10) at 20 °C, this 2½” BSP male-thread polypropylene plug delivers a robust, leak-resistant closure for the largest pipe branches typically found in pool plant rooms and irrigation headers. Moulded in black polypropylene, it resists corrosion, chlorinated water, and common pool chemicals without deteriorating. It is a straightforward, permanent or temporary cap for any female BSP-threaded port of the same size.

Material & chemical resistance

Polypropylene combines low weight with excellent resistance to chlorinated water, mild acids, alkalis, and the chemical additives common in pool and spa systems. The black colouration is UV-stabilised, making the fitting suitable for exposed above-ground pipework as well as concealed plant-room installations. Unlike metal alternatives, PP will not corrode or stain surrounding surfaces.

Thread type & sealing

The 2½” BSP male thread conforms to European standards and mates directly with female BSP sockets, valves, pump bodies, filter heads, and manifold ports of the same nominal size. A PTFE thread-seal tape wrap on assembly is all that is required for a leak-free joint at the rated 10 bar working pressure, with no additional gasket or O-ring needed.

Sizing & application

At 2½”, this is a large-diameter plug suited to commercial pool pipework, high-flow filtration systems, and industrial water-treatment manifolds where smaller plugs would be inadequate. It can cap redundant outlets on multi-port manifolds, blank off seasonal bypass lines, or serve as a pressure-test port closure during commissioning and maintenance.
