The Prima Plus Compression Reducing Set is an ideal solution for professional plumbers and DIY enthusiasts working on water or gas system transitions. These fittings allow for a reliable size reduction between 42mm and 22mm piping, offering exceptional durability and compliance with British quality standards. While the brass construction provides superior strength for long-term installations, users should ensure they have the appropriate pipe cutters and wrenches to accommodate the larger 42mm diameter during assembly.

Yes, these fittings are manufactured to high standards suitable for both water and gas systems.
No, this is a mechanical compression fitting and does not require soldering or jointing compound to create a seal.
WRAS approval indicates that the product has been tested to ensure it does not contaminate drinking water, making it safe for domestic water supply lines.
It is recommended to replace the olive if the fitting has been disassembled, as the ring becomes deformed during the initial installation to create a seal.
Yes, all Prima Plus fittings in this range are manufactured in Britain.
Tighten the nut an additional quarter-turn. If the leak persists, check if the pipe end was properly deburred.
Ensure the fitting and pipe are perfectly aligned. Cross-threading can damage the brass threads.
To install, ensure the 42mm and 22mm pipes are cut square and deburred to prevent damage to the internal olives. Slide the nut and the compression olive onto the pipe before inserting it into the fitting body. Tighten the nut by hand until firm, then complete the seal with a high-quality wrench, typically adding one half-turn to ensure the olive bites into the pipe surface. These fittings are compatible with standard copper piping of the matching dimensions. Periodically inspect joints for signs of weeping, particularly in heating systems that undergo frequent thermal expansion and contraction cycles.
