Product Information

Full details

The Primaflow Prima Plus Endfeed Slip Coupling is designed for professional plumbers and DIY enthusiasts working on copper piping systems for water and gas. It offers a secure, permanent connection that meets rigorous British quality standards, making it ideal for high-pressure drinking water applications. The primary caveat for this fitting is that it requires professional-grade soldering skills and equipment to ensure a leak-proof seal, as it is an endfeed fitting rather than a push-fit alternative.

Extended Product Information

FAQs

Is this fitting suitable for gas lines?

Yes, Prima Plus endfeed fittings are designed for both water and gas systems.

Can I use this on plastic pipes?

No, this fitting is specifically engineered for copper pipework.

What is the primary benefit of a slip coupling?

A slip coupling lacks internal pipe stops, allowing the fitting to slide fully over a pipe, which is essential for repairs or connecting pipes in fixed positions.

Does this product have WRAS approval?

Yes, it is fully WRAS approved, meaning it is safe for drinking water supply systems.

What standard do these fittings follow?

They are manufactured to EN 1254 standards and carry the British Kitemark.

Troubleshooting

Joint is leaking after soldering

The fitting may not have been heated sufficiently to draw the solder through. Clean the joint, re-flux, and re-apply heat.

Solder not flowing into the joint

Ensure the pipe and fitting are properly cleaned of oxidation and that the flux is fresh and active.

Pros and Cons

Pros

  • Meets strict EN 1254 and Kitemark standards for reliability
  • WRAS approved for drinking water safety
  • Durable copper construction ensures longevity
  • Compact design ideal for tight plumbing configurations

Cons

  • Requires soldering experience and proper equipment
  • Cannot be removed or reused once soldered
  • Not suitable for use with plastic piping materials

Setup, Compatibility & Care

To ensure a successful installation, follow these steps:

  1. Preparation: Cut the 42mm copper pipe ends square and remove all burrs using a deburring tool or file.
  2. Cleaning: Use a wire brush or emery cloth to clean the outside of the pipe and the inside of the fitting until they are bright and free of oxidation.
  3. Fluxing: Apply a thin, even coat of soldering flux to both the pipe end and the inside of the fitting.
  4. Heating: Apply heat evenly to the fitting until the solder melts upon contact with the joint, allowing the capillary action to draw the solder into the gap.
  5. Maintenance: Once installed, check for leaks while the system is under pressure. For longevity, avoid exposing the copper joints to harsh chemicals or external corrosive agents.
