Electrofusion coupling Weba PE 25 black

Electrofusion coupling Weba PE 25 black is a polyethylene coupling designed for electrofusion joining of PE pipelines with a 25 mm nominal diameter. Intended for assembly of water, gas distribution and other low-pressure utility systems, this coupling uses an embedded heating element to create a fused, leak-resistant joint between pipes. The black PE material offers UV resistance for short-term exposure during installation and matches common PE pipeline appearance.

Advantages

The electrofusion design ensures consistent heating along the joint area, producing reliable mechanical strength and a uniform fused interface without the need for external clamps or adhesives. Installation is quick compared with mechanical fittings, and the fused joint reduces the number of potential leak points. The coupling's compact size and polyethylene construction provide corrosion resistance and long-term compatibility with PE pipe systems.

Suitable for

• Joining PE pipes with 25 mm nominal diameter in water distribution networks
• Low-pressure gas distribution where thermofusion-certified fittings are accepted
• Repairs and branch connections in service lines and utility installations

Key specifications

• Material: polyethylene (PE)
• Nominal pipe size: 25 mm
• Connection type: electrofusion (embedded heating element)
• Color: black
• Suitable for: low-pressure utility pipelines (water, gas, service lines)

How to use

Prepare pipe ends by cutting square and removing burrs, then clean and scrape the fusion zone according to standard electrofusion procedures. Align the pipes in the coupling and secure them in an appropriate clamping fixture. Connect the electrofusion control unit to the coupling terminals and run the manufacturer-recommended fusion cycle. Allow the joint to cool without movement for the specified post-fusion time before releasing clamps and returning the line to service.

Usage recommendations

Use certified electrofusion equipment and follow applicable standards and safety procedures for gas or water installations. Store couplings in a dry, shaded area to minimize prolonged UV exposure. Verify compatibility of pipe material and SDR (standard dimension ratio) before fusion to ensure proper joint formation.
