## Summary description

Welded end cap for 16 mm PE-RT pipes from SiGMA-Li (model PERTZ16). Designed to seal the end of PE-RT piping systems, the cap provides a secure closure for distribution, heating, and plumbing installations. Suitable for use during pressure testing, temporary shutdowns or permanent termination of 16 mm polyethylene raised temperature (PE-RT) tubes.

## Long description

Welded end cap for 16 mm PE-RT pipes from SiGMA-Li (PERTZ16) is a purpose-designed closure that provides a reliable seal for the open end of 16 mm polyethylene raised temperature (PE-RT) tubing. The cap is manufactured to fit snugly onto 16 mm PE-RT pipe ends and is suitable for use in distribution, heating and plumbing installations where an effective, low-profile termination is required. It is intended for both temporary needs — such as pressure testing and system commissioning — and for permanent end-of-line closure when a welded, tamper-resistant finish is preferred.
Advantages
The welded end cap offers a tight, leak-resistant seal that reduces the risk of water loss and ingress of contaminants. Its design ensures compatibility with 16 mm PE-RT pipes and enables a straightforward welding installation that creates a durable joint. The welded connection provides mechanical integrity and resists accidental dislodgement compared with non-welded closures. The cap’s low profile and material selection support longevity in typical plumbing and heating environments.
Suitable for
Sealing the end of 16 mm PE-RT supply and return lines in underfloor heating systems
Temporary closure during pressure testing and commissioning of PE-RT pipework
Permanent end termination of distribution and plumbing loops using 16 mm PE-RT tubing
Sites where a welded, tamper-resistant finish is required for safety or maintenance reasons
Key specifications
Compatibility: designed for 16 mm PE-RT (polyethylene raised temperature) pipes
Connection type: welded end cap for permanent or temporary welded closure
Typical applications: heating, plumbing and distribution systems
Profile: low-profile end cap to minimize protrusion from pipe end
How to use
Prepare the 16 mm PE-RT pipe end by cutting squarely and ensuring it is clean and free from debris. Position the welded end cap over the pipe end and perform the appropriate welding/joining procedure recommended for PE-RT materials and the chosen equipment. After welding, allow the joint to cool and inspect the seal visually and, where applicable, by pressure testing according to the system specifications. Use the cap for temporary closures during testing or as a permanent termination once proper welding and verification have been completed.
Usage recommendations
Use approved PE-RT welding tools and follow industry-standard welding parameters for temperature and time. Verify joint integrity with pressure testing after installation and avoid mechanical stresses on the welded cap during system operation.
