End Cap KAN-therm PP 40 mm grey 04110040

The KAN-therm PP end cap 40 mm in grey is a polypropylene fitting designed to seal the open end of 40 mm pipes in plumbing and heating systems. It provides a reliable closure for pipe runs, branch connections or service openings, allowing temporary or permanent sealing during installation, pressure testing and maintenance. The fitting is made of PP, compatible with common plastic piping systems, and is intended to protect the pipeline from dirt, moisture and mechanical intrusion when a secure end cap is required.

Advantages

This end cap is manufactured from polypropylene, which ensures chemical resistance and dimensional stability in typical indoor plumbing and heating environments. Its simple push-fit design enables quick application without special tools for temporary sealing, while the durable material allows long-term use when a permanent closure is needed. The neutral grey colour aids visual identification on site and the compact form provides secure coverage for 40 mm pipe ends.

Suitable for

• Sealing open ends of 40 mm plastic pipe runs
• Temporary closures for pressure testing and leak detection
• Protecting pipe interiors during construction and renovation
• Blocking unused branch connections in heating and plumbing installations

Key specifications

• Material: polypropylene (PP)
• Nominal pipe size: 40 mm
• Colour: grey
• Application: end cap for sealing pipe ends and branch connections
• Suitable for temporary or permanent sealing

How to use

Ensure the pipe end is clean and free of debris, burrs or sharp edges. Align the end cap with the pipe axis and press it onto the 40 mm pipe until fully seated. For a secure fit, apply steady pressure and check that the cap covers the pipe circumference evenly. For pressure testing, verify compatibility of the cap with the test medium and follow system test procedures. To remove, pull the cap from the pipe using an appropriate grip; if permanently attached, follow the installer’s method for removal or replacement.

Usage recommendations

Use the end cap only on 40 mm polypropylene or compatible plastic pipes. Avoid exposure to open flames and continuous temperatures beyond the material’s typical service range. For pressure testing, confirm that the fitting's sealing method is suitable for the required test pressure and duration. Store caps in a dry, shaded area before installation to preserve material properties.
