Electrofusion End Cap
Radius Systems electrofusion end caps permanently close the end of compatible polyethylene pressure pipe. The construction varies by size, so select by the exact pipe outside diameter and SKU rather than assuming every cap is a single moulding.

Reference data from Radius Systems' 2024 electrofusion fittings brochure. Always use the instructions on the actual fitting and packaging; current label data takes priority over this reference table.
Confirmed specification
- High-strength PE100 fitting with exposed-wire electrofusion technology.
- 40 V fitting with 4.0 mm terminal pins for all listed variants.
- Radius classifies this end-cap family as universal and publishes a family maximum operating pressure of 16 bar. Confirm the individual fitting approval, pipe SDR, service and permitted operating pressure before installation.
- Creates an end-load-bearing termination when correctly installed; it is not a removable stop end.
Installation essentials
- Keep the fitting sealed in its packaging until the pipe is prepared. Work in a clean, dry, sheltered area.
- Cut the pipe square. Scrape with an approved tool without over-scraping, then avoid touching or wiping the prepared surface.
- Re-round oval pipe where required, insert fully to the fitting stop and secure with an alignment clamp.
- Use compatible, calibrated 40 V electrofusion equipment. Keep the clamp in place for the complete fusion and cooling cycles.
- Do not reheat after an interrupted cycle. Check the control box completed without error and inspect the joint before commissioning.
See the three supporting gallery images for Radius Systems’ preparation, equipment, fusion, cooling and quality guidance for these socket fittings. Use trained, competent installers and appropriate protective footwear, eye protection and gloves. Follow the actual fitting’s voltage, fusion and cooling instructions; keep clamps in place throughout both cycles. Do not reheat or commission a fitting after an interrupted cycle. A raised fusion indicator does not prove joint quality: inspect the joint, check the control-box result, retain fusion records and joint references, and pressure-test by the approved procedure before commissioning.
