Electrofusion Socket
Radius Systems electrofusion sockets - also described by Radius as couplers - join two compatible polyethylene pressure pipes of the same outside diameter. They form a permanent, end-load-bearing joint when correctly installed.

Reference data from Radius Systems' 2024 electrofusion fittings brochure. Always follow the data on the supplied fitting and packaging; current label values take priority.
Confirmed specification
- Black, high-strength PE100 coupler with exposed-wire electrofusion zones and insertion stops.
- 40 V fitting with 4.0 mm terminal pins for all listed variants.
- Radius' current product selector identifies these exact codes for 16 bar water and 10 bar gas applications. The permitted operating pressure still depends on the service, pipe SDR, approval and project specification.
- Tested for compatible PE80 and PE100 pipe across a range of SDRs.
Installation essentials
- Keep the socket packaged until both pipe ends are prepared. Work in a clean, dry, sheltered area.
- Cut both ends square. Scrape evenly with an approved tool without over-scraping, then do not touch or wipe the prepared surfaces.
- Re-round oval pipe where required. Insert both ends fully to the internal stops and secure with alignment clamps.
- Use compatible, calibrated 40 V electrofusion equipment capable of completing the cycle without interruption. Leave clamps in place throughout fusion and cooling.
- Do not reheat a fitting after an interrupted cycle. Confirm 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.
