Pipe end cap Supratherm 20 mm model 2204050 for PP-R plumbing systems

Supratherm PP‑R pipe end cap, model 2204050, 20 mm, is designed to close and seal the open end of polypropylene random copolymer (PP‑R) plumbing pipes. The cap provides a durable, leak‑resistant termination suitable for potable water and heating installations and can be used for temporary or permanent pipe closures during installation and maintenance. PP‑R material is lightweight while offering high impact resistance, abrasion resistance and chemical resistance, and is rated for operation at temperatures up to 90ºC.

Advantages

The Supratherm 20 mm end cap is compact and easy to install, ensuring a tight seal on PP‑R piping systems to prevent leaks. Made from PP‑R, it combines low weight with good mechanical strength and chemical durability, making it suitable for both cold and hot water systems as well as heating and air‑conditioning applications. The model 2204050 is compatible with standard 20 mm PP‑R pipe dimensions.

Suitable for (tasks / use cases)

• Sealing the end of 20 mm PP‑R pipes during installation
• Temporary closures during maintenance or pressure testing
• Permanent termination of pipe runs in potable water systems
• Closing supply lines in heating and air‑conditioning circuits

How to use

Prepare the pipe end by cutting squarely and deburring to ensure a clean surface. Fit the Supratherm PP‑R end cap onto the prepared 20 mm pipe end and join according to the PP‑R welding or socket‑fusion method recommended for the system (ensure appropriate equipment and trained personnel are used). For temporary closures, verify the seal after cooling and during pressure testing; for permanent installations follow local plumbing codes and installation standards.

Usage recommendations

Use compatible PP‑R joining methods and follow manufacturer and local regulations. Do not exceed the rated temperature (90ºC) and inspect joints for leaks after installation. For critical systems, use qualified installers and perform pressure tests as required.
