FAQs

Are these fittings safe for drinking water?

Yes, PRIMA CLASSIC 8mm Endfeed Couplings are fully WRAS approved, confirming they meet all safety requirements for potable water systems.

Can I use these for gas lines?

Yes, these fittings are suitable for use in gas installations, provided they are installed according to local building regulations and safety standards.

What is the maximum pressure these can handle?

These fittings are designed to operate within the standard pressure ratings for EN 1254 compliant copper fittings typically found in domestic plumbing.

Do I need special tools to install these?

Yes, you will need a pipe cutter, a deburring tool, cleaning abrasive, plumbing flux, and a soldering torch with appropriate solder.

Can these be used with plastic pipes?

No, these are strictly for copper piping and are not compatible with plastic pipe inserts or systems.

Troubleshooting

Solder fails to flow into the joint

Ensure the surfaces were properly cleaned of oxidation and that sufficient flux was applied. Check that the fitting and pipe are heated evenly.

Joint leaks after cooling

This is often caused by gaps or overheating the flux. The fitting must be unsoldered, cleaned thoroughly, and re-soldered with proper heat management.

Pros and Cons

Pros

  • High-quality copper construction ensures long-term durability
  • WRAS approval guarantees safety for drinking water installations
  • Consistent sizing makes for easy alignment and installation
  • Suitable for a wide range of water and gas plumbing projects

Cons

  • Requires professional soldering equipment and experience
  • Not intended for non-copper piping materials
  • Installation is permanent once soldered

Setup, Compatibility & Care

To ensure a successful installation, follow these steps:

  1. Preparation: Cut the 8mm copper pipe cleanly using a pipe cutter to avoid burrs. De-burr the end of the pipe using a file or reamer.
  2. Cleaning: Use a wire brush or fine abrasive cloth to clean both the outside of the pipe and the inside of the coupling until bright.
  3. Fluxing: Apply a thin, even coat of soldering flux to both cleaned surfaces.
  4. Soldering: Insert the pipe fully into the fitting. Apply heat evenly to the fitting until the solder flows into the joint via capillary action.
  5. Finishing: Allow the joint to cool naturally; do not quench with water. Wipe away excess flux with a damp cloth to prevent future corrosion.

Compatibility is strictly limited to 8mm copper piping. These fittings are not designed for PEX, plastic, or stainless steel systems.
