FAQs

What is the primary use for this adaptor?

This adaptor is used to connect pipes in water and gas installations, specifically for joining a 35mm pipe to a 1 1/4 inch male iron threaded fitting.

Is this fitting suitable for drinking water?

Yes, the Prima Classic compression adaptor is WRAS approved, making it safe and suitable for use with potable (drinking) water systems.

What does EN 1254 standard mean?

EN 1254 is a European standard that specifies requirements for copper and copper alloy fittings used in plumbing and gas installations, ensuring quality and safety.

Do I need any special tools to install this fitting?

You will need appropriate pipe cutters to ensure a clean, square cut on the pipe, and two wrenches (one to hold the fitting body, one to tighten the compression nut).

Can this fitting be used for gas lines?

Yes, Prima Classic compression fittings are suitable for gas installations, provided they are rated for gas and installed according to relevant gas safety regulations.

What is the difference between the 35mm and 1 1/4 Mi connections?

The 35mm refers to the outside diameter of the pipe it connects to via compression. The 1 1/4" Mi (Male Iron) refers to a standard threaded connection size for connecting to other threaded fittings or components.

Troubleshooting

Leak at the connection

Ensure the pipe is fully inserted and seated. Check that the olive is correctly positioned. Try tightening the compression nut slightly more, being careful not to overtighten.

Difficulty tightening the nut

Verify that the pipe is not damaged and is correctly sized. Ensure the threads on the adaptor and nut are clean and free of debris.

Fitting does not seal properly after tightening

The pipe surface may be uneven or damaged. Ensure the pipe is cut squarely and is smooth. Replace the olive if it appears damaged.

Pros and Cons

Pros

  • Excellent value for money.
  • Certified safe for drinking water (WRAS approved).
  • Robust brass construction ensures durability.
  • Complies with international EN 1254 standard.
  • Suitable for both water and gas lines.

Cons

  • Requires proper pipe preparation for a secure seal.
  • Compression fittings may require re-tightening over time.

Setup, Compatibility & Care

Setup:

  1. Ensure the pipe ends are clean, smooth, and free from damage. Cut the pipe squarely.
  2. Slide the compression nut over the pipe, followed by the compression olive.
  3. Insert the pipe into the adaptor body, ensuring it is fully seated.
  4. Slide the olive and nut up to the fitting and hand-tighten the nut.
  5. Using an appropriate wrench, tighten the nut a further 1/2 to 1 full turn to secure the olive onto the pipe and create a seal. Do not overtighten.

Compatibility:

  • Compatible with copper, brass, and other suitable pipe materials that fit the specified dimensions.
  • Ensure the system pressure and temperature ratings are within the product's specifications. WRAS approval confirms suitability for potable water systems.

Care:

  • Periodically check compression fittings for any signs of leakage, especially after initial installation or if the system experiences significant temperature or pressure fluctuations.
  • If a leak is detected, carefully tighten the compression nut slightly. Avoid overtightening, which can damage the fitting or pipe.
