Product Information

Full details

The Prima Plus Compression Reducing Set is an ideal solution for professional plumbers and experienced DIYers who need to join two pipes of different diameters securely. Designed for both water and gas installations, these premium brass fittings offer high reliability and a leak-proof connection; however, they require precise tightening to ensure the internal olive seals correctly against the different pipe sizes.

FAQs

Can I use these for gas pipes?

Yes, these fittings are suitable for both water and gas installations.

Are these fittings WRAS approved?

Yes, they are fully WRAS approved, making them safe for use with drinking water.

Do I need to use solder with these fittings?

No, these are compression fittings and do not require heat or solder for a secure seal.

What standards do these fittings meet?

They are manufactured to the EN 1254 standard and carry the British Kite mark.

Can these be reused?

While the brass body can often be reused, it is highly recommended to use a new olive every time a joint is disconnected and reconnected.

Troubleshooting

Joint is weeping or leaking

Ensure the nut is tightened further. If the leak persists, disconnect and inspect the olive for scratches or deformation, and replace it if necessary.

Difficulty tightening the nut

Check that the threads are not crossed and that the pipe is inserted perfectly straight into the fitting body.

Pros and Cons

Pros

  • Certified for drinking water (WRAS approved)
  • Durable, high-quality brass material
  • Easy to install without soldering
  • Kite marked for reliability and quality assurance

Cons

  • Requires proper tools for tightening
  • Not suitable for use with certain thin-walled plastic pipes without appropriate inserts
  • Requires careful alignment to prevent cross-threading

Setup, Compatibility & Care

To install, ensure the pipe is clean and free of debris. When tightening the nut, apply steady pressure with a wrench until you feel a firm resistance, typically adding a quarter to half a turn beyond hand-tight to compress the olive effectively. For maintenance, periodically inspect connections for signs of weeping, especially in gas systems. Ensure you are using the correct size reducers for your pipe material; if using with soft copper, ensure the pipe is not deformed during installation.
