PPR 20mm Female Elbow, PN25 Brass-Threaded Plumbing Fitting

20mm PPR Female Elbow

The PPR 20mm Female Elbow provides a robust transition point between heat-fused piping and threaded hardware in pressurized water systems. This fitting combines high-density polypropylene random copolymer with a heavy-duty brass insert to facilitate secure connections to faucets or valves. It serves as a critical junction in both residential and industrial potable water networks.

Built for the Job

This component is engineered for thermal fusion welding, creating a monolithic bond that eliminates traditional leak paths found in mechanical joints. The internal brass threading handles high torque during installation without cracking the housing. Site supervisors specify this hardware for hot and cold water distribution due to its high PN25 pressure rating and resistance to scale buildup. It maintains structural integrity even when subjected to significant thermal cycling in boiler loops or solar water heating installations.

• Connecting 20mm PPR main lines to 1/2-inch threaded chrome bathroom fixtures.

• Installing pressure gauges or air release valves in pump house manifolds.

• Terminating wall-mounted pipe runs for kitchen mixer tap assemblies.

Product Highlights

PN25 Pressure Certification

The fitting supports a working pressure of up to 2.5 MPa, making it suitable for high-rise riser pipes.

Brass Insert Engineering

• Deep-seated knurled brass prevents rotation within the plastic body during tightening.
• Precision-cut female threads ensure a watertight seal with standard BSP male fittings.

Technical Specifications

What’s Included

• 1 x 20mm PPR Female Threaded Elbow (Brass Insert)

On-Site & Workshop Notes

• Ensure the fusion tool is heated to exactly 260°C before attempting to join the 20mm socket.

• Do not over-tighten metal male fittings into the brass seat to avoid unnecessary stress on the polymer housing.

• Use high-quality PTFE tape or thread sealant on the female threads to ensure a permanent, leak-free connection.

• Avoid exposing the polypropylene sections to direct UV light for extended periods during outdoor storage.
