Nipple PP 1¼" Male Thread 10 bar Black - 0121138

Nipple PP 1¼” Male Thread 10 bar Black

Rated to 10 bar working pressure and tolerant of temperatures up to 60 °C, this 1¼” male-threaded polypropylene nipple is an essential plumbing component for pool plant rooms, salt-chlorinator installations, and chemical-dosing systems. Its BSP male threads at both ends allow a secure, leak-free connection between two female-threaded fittings, valves, or inline equipment. The black PP construction offers excellent resistance to chlorinated water and common pool chemicals.

Material & chemical resistance

Moulded from polypropylene (PP), this nipple is inherently resistant to chlorine, saltwater, and the mild acids or alkalis used in pool water treatment. PP fittings are lightweight yet dimensionally stable, making them well suited to the warm, chemically active environment found in a pool or spa plant room.

Pressure & temperature rating

The 10 bar pressure rating provides a substantial safety margin for typical pool circulation systems, which rarely exceed 3–4 bar in normal operation. The 60 °C maximum temperature rating also makes this nipple compatible with heated pool lines and heat-pump connections where water temperatures are elevated.

Installation & compatibility

The 1¼” BSP male thread is one of the most common sizes found on pool pump volutes, filter multiport valve ports, and chemical-dosing injectors across European pool systems. The fitting can be assembled with PTFE tape or thread sealant and requires no specialist tooling, making it straightforward for installers or competent DIY users to fit quickly.
