25 mm PPR Equal Coupling
This 25 mm PPR equal coupling connects two pipes of the same diameter in hot and cold water systems. The fitting uses a welding end connection to create a seamless, leak-proof joint. Rated for PN25 pressure and a 0-75°C temperature range, it suits residential and commercial plumbing installations. The ISO-certified PPR body resists corrosion and chemical attack for long service life.
Installers needing a straight, same-size joint
Plumbers joining 25 mm PPR pipe runs in potable water, heating or cooling circuits will find this coupling matches the required pressure and temperature ratings. It is not intended for systems operating above 75°C or beyond PN25 pressure. Buyers who need a reducing coupling, threaded adapter or a different pipe diameter should select another fitting type.
Heat-fusion welding required
Installation is performed with standard PPR socket-fusion or butt-fusion tools, producing a homogeneous joint without separate sealants. The smooth interior surface maintains flow once the weld cools. Common issues arise if pipe ends are not cut square, if the heating depth is insufficient, or if the joint is disturbed before the fusion sets fully.

Questions about this item
Do I need a 25 mm PPR pipe and a heat-fusion tool to install this equal coupling?
Yes, the fitting is designed for 25 mm PPR pipe and uses welding end connections, so a compatible heat-fusion tool is required to create the joint.
Can this PN25 coupling stay in a system that still has older metal fittings rated for lower pressure?
The coupling handles up to PN25 and 0-75 °C, but the overall system pressure must not exceed the lowest-rated component, so verify the older fittings' limits before pressurising.
How can I confirm the 25 mm weld joint is leak-free after installation?
Pressurise the line with water up to the system's working pressure and inspect the fused joint; a correctly fused PPR connection shows no seepage at the coupling.
