Nipple PP 1½" Male Thread 10 bar Black - 0121139

Nipple PP 1½” Male Thread 10 bar Black

Rated to 10 bar at 20 °C and tolerating temperatures up to 60 °C, this 1½” BSP male-threaded polypropylene nipple is a compact male-to-male connector designed to bridge two female-threaded fittings in pool plant rooms, chlorination systems, and pressurised water circuits. The 1½” (approx. 47.8 mm) thread size is one of the most common in pool pipework, making it a practical stock item for installers and dealers alike.

Material & chemical resistance

Moulded from impact-resistant polypropylene (PP), this nipple offers strong resistance to chlorinated water, salt solutions, mild acids, and other chemicals routinely encountered in pool treatment systems. PP does not corrode, scale, or degrade in the presence of chlorine or salt — a significant advantage over brass or steel equivalents in a pool environment.

Pressure & temperature performance

With a 10 bar pressure rating, this fitting comfortably handles the working pressures generated by standard pool circulation pumps and dosing systems. The 60 °C maximum temperature rating also makes it suitable for use on the outlet side of pool heat pumps and solar heating circuits where pipework sees elevated temperatures.

Thread & connection

The BSP male thread on both ends connects directly to any standard female BSP socket, valve, pump port, or filter head of the same size. Standard PTFE thread tape or liquid thread sealant is recommended to achieve a reliable, drip-free seal. The black colouring blends unobtrusively into plant room pipework.
