## Summary description

Electrofusion coupling REHAU Mufa elektrooporowa - 40 is a REHAU-brand fitting for joining polyethylene (PE) pipes with a nominal diameter of 40 mm. Designed for electrofusion welding, it provides a reliable, permanent joint suitable for water, gas distribution and other low-pressure piping systems where PE pipe connections are required.

## Long description

Electrofusion coupling REHAU Mufa elektrooporowa - 40 is a REHAU-brand fitting for joining polyethylene (PE) pipes with a nominal diameter of 40 mm. It is designed for electrofusion welding to create permanent joints between PE pipes used in water distribution, low-pressure gas networks and other piping systems where PE connections are required. The coupling integrates an embedded heating element to produce a controlled fusion zone that bonds pipe and fitting into a continuous, leak-resistant joint.
Advantages
The electrofusion coupling provides a durable, corrosion-resistant connection compatible with PE materials and suitable for in-ground or aboveground installations. Its integrated heating coil ensures consistent fusion parameters when used with an appropriate electrofusion control unit, reducing variability compared with manual butt fusion methods. Installation is relatively fast and minimizes the need for mechanical clamps or additional sealing materials.
Suitable for
Joining PE pipes with 40 mm nominal diameter
Water distribution and supply networks (low to medium pressure)
Low-pressure gas distribution systems where PE fittings are approved
Repairing or extending existing polyethylene piping runs
When it may not be suitable
This coupling is intended specifically for polyethylene (PE) pipes of the stated diameter and is not suitable for metal, PVC, or non-compatible plastic pipes. It requires an electrofusion control unit and compatible procedures; without appropriate equipment and trained personnel, the joint may not achieve the required mechanical strength and leak-tightness. For high-pressure applications or where different materials must be connected, alternative fittings or adapters should be considered.
Key specifications
Material compatibility: polyethylene (PE)
Nominal pipe diameter: 40 mm
Connection type: electrofusion coupling with embedded heating element
Application: water and low-pressure gas distribution, general PE pipeline systems
Installation method: electrofusion welding using a compatible control unit
How to use
Prepare pipe ends by cutting squarely and cleaning to remove dirt, grease and oxidation. Mark insertion depth on the pipe, align pipes within the coupling and secure them to prevent movement. Use the appropriate electrofusion control unit with settings recommended for a 40 mm REHAU electrofusion coupling; connect the welding leads, follow the control unit prompts and execute the fusion cycle. After fusion, allow the cooling time specified by the control unit before handling or putting the joint into service. Follow local codes and REHAU installation guidelines for pressures, testing and backfilling.
What to consider before purchase
Compatibility with polyethylene (PE) pipe material and 40 mm nominal diameter
Availability of a compatible electrofusion control unit and trained operator
Intended application (water, gas, buried or exposed installation) and applicable standards or approvals
Quantity needed for the project and any complementary fittings or tools required
Usage recommendations
Use with a calibrated electrofusion control unit and follow REHAU or industry-approved fusion procedures. Ensure pipe ends are clean and properly prepared, and allow specified cooling time after welding. Perform pressure testing according to local regulations before commissioning the pipeline.
