Pipe adapter Supratherm 20x1/2M coupling PP‑R 20 mm to 1/2" male thread

Supratherm PP‑R adapter 20x1/2M is a pipe fitting designed to connect 20 mm polypropylene‑random (PP‑R) pipe to a 1/2" male threaded connection. The adapter provides a compact, leak‑resistant junction that enables transition between plastic PP‑R piping and threaded valves or fixtures in plumbing, heating and air conditioning systems. PP‑R materials are lightweight while offering high impact, abrasion and chemical resistance; they are suitable for use at temperatures up to 90°C.

Advantages

The Supratherm 20x1/2M coupling combines PP‑R corrosion and chemical resistance with a threaded metal interface for easy connection to standard fittings. Its construction ensures reliable sealing when installed correctly and reduces the need for complex transition components. The fitting is compact and suitable for use in both domestic and commercial installations.

Suitable for

• Connecting 20 mm PP‑R pipe to 1/2" male threaded valves and fixtures
• Domestic hot and cold water systems
• Heating systems and radiator connections
• HVAC systems where transition from plastic pipework to threaded components is required

Key specifications

• Brand: Supratherm
• Model / MPN: 2204210
• EAN: 5945792204210
• Connection: 20 mm PP‑R socket to 1/2" male thread
• Material: PP‑R (polypropylene‑random) with threaded metal interface
• Maximum recommended temperature: up to 90°C

How to use

Install the adapter by preparing the PP‑R pipe end according to standard PP‑R joining procedures (cut square, clean and heat‑fusion or socket fusion as required). Screw the 1/2" male thread into the corresponding female threaded fitting, using appropriate sealing tape or sealant on the threads if recommended for the installation. Ensure correct alignment and allow any fused joints to cool fully before pressurising the system.

Usage recommendations

Use this adapter in systems within the specified temperature range (up to 90°C) and follow local plumbing codes. Verify compatibility of thread type and size with existing fittings and apply proper heat‑fusion techniques for PP‑R to ensure leak‑free, long‑lasting joints.
