17mm Plastic x 15mm Copper Reducer

The 17mm x 15mm reducer allows you to connect 17mm plastic underfloor heating pipe directly to 15mm copper pipework. Compression fittings and olives on both sides create a secure, reliable joint that minimises the risk of leaks — no soldering required.

Commonly used when connecting UFH pipe runs to existing copper installations, or when transitioning between plastic manifold connections and copper supply pipework.

Compatible with: 17mm PERT-AL-PERT and EVOH underfloor heating pipe and standard 15mm copper tube.
