First hot tapping system for PE-Xa heating pipes

Redefining Limits

Tapping with REHAU NEXUS – fast and safe
What used to be only possible for cold water, gas and steel pipe heating systems is now available for hot water: NEXUS, the first hot tapping system for PE-Xa heating pipes. Exclusively from REHAU.

Versatile use without supply disruption
Want to expand your network? Or retrofit ventilation or monitoring points? No problem! No matter what you want to achieve, REHAU NEXUS allows you to carry out expansions directly during the heating process and under.

A complete system, one contact
REHAU NEXUS fits perfectly into our existing product portfolio. For you, this means maximum convenience with nearly zero coordination effort, because we provide you with a perfectly coordinated complete system (consisting pipe, fitting, tool and coupling) from a single source. Of course, training is also provided.

Flexible in integration, uncomprimising resistance
Whether underground or directly in the heating system – REHAU NEXUS is suitable for all** pre-insulated REHAU pipe systems – without compromise, because the overall system retains its minimum lifetime of 30 years (in accordance with EN15632). For particularly convenient integration, you receive clamps in dimensions d63 – d125, compression sleeve adapters in dimensions d25 – d40 and a universal adapter for the transition with a 1 inch female thread.
