Pipe cap Supratherm Cap PP-R 40 for PP‑R piping systems, size 40 mm

Supratherm Cap PP-R 40 is a polypropylene-random (PP‑R) pipe end cap for closing and sealing 40 mm PP‑R pipes. The cap is corrosion-resistant, lightweight and suitable for plumbing, heating and potable water installations. It is compatible with PP‑R fusion welding and can be used for commissioning, maintenance or permanent termination of pipeline sections.

Advantages

The PP‑R cap offers high impact resistance, good wear and chemical resistance and reliable performance at temperatures up to 90ºC. Its low weight simplifies handling and installation while providing a leak‑tight closure when correctly welded to PP‑R piping systems.

Suitable for

• Sealing the end of 40 mm PP‑R pipe runs
• Temporary closure during system commissioning or maintenance
• Permanent termination of plumbing, heating and potable water lines
• Applications requiring corrosion and chemical resistance

How to use

Prepare the pipe end by cutting squarely and removing any debris. Use the appropriate PP‑R fusion welding tool to heat and fuse the cap to the 40 mm pipe according to the welding equipment manufacturer’s instructions. Ensure correct alignment and allow the joint to cool undisturbed to form a secure, leak‑tight seal.

Usage recommendations

For durable, safe joints, follow established PP‑R fusion welding procedures, use tools sized for 40 mm fittings, and verify that service temperature and media are compatible with PP‑R material limits.
