Standard PPR Female Adapter Elbow 20mm x 1/2 Inch PN25

Standard PPR 20mm Elbow

The Standard PPR Female Adapter Elbow 20mm x 1/2 Inch PN25 facilitates a secure 90-degree transition between 20mm Polypropylene Random Copolymer piping and 1/2-inch male threaded components. This heavy-duty fitting utilizes a high-grade brass insert to ensure leak-proof connections in pressurized hot and cold water systems.

Built for the Job

Plumbing contractors utilize this 90-degree connector for terminating pipe runs at tap points, shower mixers, and manifold connections. The PN25 rating makes it suitable for high-pressure environments, including multi-story residential builds and industrial fluid transport. Because the internal bore remains smooth after fusion, it maintains high flow rates and resists scale buildup over decades of service.

• Terminating water lines for wall-mounted faucets and mixers.

• Transitioning from PPR mains to metallic valves or flexible hoses.

• Installation in concealed wall chases for bathroom and kitchen sets.

Product Highlights

High-Pressure PN25 Rating

This fitting withstands working pressures up to 25 bar, providing a significant safety margin for pump-fed systems.

Reinforced Brass Interface

• Deep-seated brass threads resist cross-threading during installation.
• Knurled external brass surface prevents rotation within the plastic housing.

Technical Specifications

What’s Included

On-Site & Workshop Notes

• Ensure the socket fusion welder is set to 260°C before attempting the joint.

• Maintain a heating time of approximately 5 seconds for the 20mm socket to avoid over-melting the bore.

• Apply PTFE tape or thread sealant to the 1/2 inch male counterpart to ensure a watertight seal with the brass insert.

• Avoid excessive torque when tightening metallic fittings into the threaded section to prevent stress cracking in the polymer body.
