Standard PPR 20mm x 1/2 Inch Male Adapter Elbow, PN25 Pressure Rated

20mm x 1/2 Inch Male Adapter Elbow

The PPR Male Adapter Elbow serves as a specialized plumbing component designed to transition between high-density polypropylene piping and metallic threaded fixtures. This fitting integrates a 20mm socket fusion end with a 1/2 inch male threaded brass insert, facilitating secure connections for terminal units. It meets the rigorous demands of pressurized hot and cold water distribution systems in residential and commercial developments.

Built for the Job

Plumbing contractors utilize this 90-degree fitting when installing faucets, shower mixers, or manifold connections where a change in direction and material is required. The robust construction handles the thermal expansion typical in solar water heating loops and boiler return lines. Its design ensures a leak-proof interface between the plastic pipe run and various valves or appliances found on a modern site.

• Connecting PPR pipe networks to female-threaded brass gate valves or ball valves.

• Installing terminal water points for kitchen sinks and bathroom washbasins.

• Adapting plastic distribution lines to metallic pump housings or pressure tanks.

Product Highlights

Pressure Performance

The PN25 rating ensures the fitting withstands internal pressures up to 2.5 MPa at standard ambient temperatures.

Material Integrity

• High-grade Polypropylene Random Copolymer (Type 3) for superior heat resistance.
• Reinforced brass insert with deep knurling to prevent rotation during high-torque tightening.
• Smooth internal bore reduces friction loss and prevents lime-scale accumulation over time.

Technical Specifications

What’s Included

• 1 x 20mm x 1/2″ PPR Male Threaded Adapter Elbow

On-Site & Workshop Notes

• Ensure the welding iron reaches 260°C before attempting the fusion bond on the 20mm socket side.

• Avoid excessive use of thread sealant; a moderate amount of PTFE tape is sufficient for the 1/2 inch male interface.

• Do not rotate the fitting once the pipe and socket are joined during the heating or cooling phase to maintain molecular bond integrity.

• Store in a cool area away from direct UV exposure to prevent long-term degradation of the polymer structure before installation.
