ifan PPR Coupling 25mm PN25 0-75°C

25 mm PPR Coupling for Water Systems

This coupling is a straight equal connector made from PPR polymer for hot and cold water distribution. It joins two 25 mm pipes by heat-fusion welding to create a leak-proof joint without threads or sealants. The fitting meets ISO standards and carries a PN25 pressure rating for demanding plumbing installations. It operates reliably from 0 °C up to 75 °C in residential and commercial pipework.

Suited for installers building fused PPR networks

Plumbers who need a permanent, corrosion-free joint on 25 mm lines will find this coupling matches the pipe material and pressure class exactly. Projects that require threaded adaptors, compression fittings or metal-to-plastic transitions cannot use this fitting because it offers only a plain welding end. Systems running above 75 °C or above PN25 pressure also fall outside the certified range.

Behaviour under continuous pressure and temperature

The PPR body resists creep and stress relaxation when held at PN25 pressure for long periods, keeping the fused joint tight without retightening. Its smooth bore prevents scale build-up that would otherwise increase friction loss over years of service. The material remains stable through repeated thermal cycles between cold supply and 75 °C hot water, avoiding the embrittlement seen in lesser plastics.
