ifan PPR Fitting 25mm PN25 75°C Welding

25 mm PPR Welding Fitting PN25

This 25 mm PPR fitting is designed for hot and cold water distribution in residential and commercial plumbing systems. It connects tubing of the same diameter using heat-fusion welding for a permanent, leak-proof joint. The body meets ISO standards and carries a PN25 pressure rating for demanding installations. It suits installers who need a corrosion-free alternative to metal couplings.

Sustained pressure and temperature performance

The fitting maintains structural integrity across a 0–75 °C service range while continuously rated at PN25. PPR material resists scale build-up and chemical attack, so flow capacity stays consistent over years of daily cycling. No degradation from UV exposure or water treatment chemicals occurs under normal operating conditions. The smooth bore minimises friction losses during prolonged high-volume draw.

Heat-fusion installation and common pitfalls

Socket fusion requires a calibrated heating tool and precise insertion depth; under-heating leaves a weak bond while overheating deforms the socket. Pipe ends must be cut square, deburred and cleaned of moisture or debris before welding. Misalignment during the cooling phase creates stress concentrations that lead to premature failure. The single-piece carton contains no gaskets or thread sealant, so the joint relies entirely on correct fusion technique.
