PP-R pipe fitting Supratherm 25×3/4" M coupling 2204463

PP-R pipe coupling Supratherm 25×3/4" M (MPN 2204463) is a polypropylene random copolymer transition fitting designed to connect a 25 mm PP‑R pipe to a 3/4" male threaded component. The fitting is lightweight, resistant to impact, abrasion and many chemicals, and is suitable for use in potable water and heating systems at temperatures up to 90°C. Supratherm PP‑R fittings are commonly used in domestic plumbing, radiator and boiler connections, air conditioning and industrial process piping.

Advantages

The Supratherm PP‑R coupling offers corrosion resistance and a low weight while maintaining high mechanical strength. It provides durable, leak‑resistant joints when welded or sealed correctly and tolerates temperatures up to 90°C. The material resists wear and many common chemicals, reducing maintenance needs in water and heating installations.

Suitable for

• Connecting 25 mm PP‑R pipes to 3/4" male threaded fittings
• Domestic cold and hot water supply systems
• Radiator and boiler connections in heating systems
• Repair and retrofit work on PP‑R piping

How to use

Prepare the 25 mm PP‑R pipe end by cutting squarely and cleaning from debris. Join the PP‑R pipe to the coupling by appropriate socket welding (fusion) following manufacturer welding instructions, or if connecting to the threaded component, ensure the male thread is sealed with suitable thread sealant (PTFE tape or liquid sealant) and tightened to appropriate torque. Verify alignment and allow welded joints to cool before applying system pressure. Follow local plumbing codes and Supratherm installation guidelines for reliable, long‑lasting connections.

Usage recommendations

Use the fitting within the manufacturer’s temperature limit (up to 90°C). For potable water and heating installations, follow approved welding procedures and local regulations. When connecting to threaded components, use compatible thread sealants and check for leaks after pressure testing. Avoid exposure to aggressive chemicals not listed as compatible with PP‑R.
