Pipe end cap Supratherm PP-R 32 mm model 2204074 — polypropylene cap for 32 mm pipelines

Supratherm PP-R 32 mm end cap model 2204074 is a polypropylene cap designed to close and seal PP-R piping systems. Lightweight and chemically resistant, this cap provides a corrosion-free termination for 32 mm PP-R pipelines used in potable water, heating and various industrial plastic installations. It is intended for welded or socket joint connections and suitable for operation at temperatures up to 90ºC.

Advantages

The polypropylene construction ensures low weight, high impact and wear resistance, and chemical durability. The cap provides reliable sealing for pipeline terminations, simplifies pressure testing and maintenance, and resists corrosion compared with metal alternatives. It is compatible with standard 32 mm PP-R fittings and supports long service life in typical water and heating applications.

Suitable for

• Sealing and terminating 32 mm PP-R pipelines
• Domestic and commercial potable water systems
• Heating systems and radiators
• Industrial plastic piping where chemical and corrosion resistance is required
