This guide is for plumbers and DIY enthusiasts working with water and gas installations. The Prima Plus Solder Ring Adaptor Coupler offers a significant time-saving benefit by integrating solder directly into the fitting, eliminating the need for external solder. A key consideration is the imperial pipe sizing, where the 1" side measures 28.24mm in diameter. This product is a premium copper fitting designed for reliable connections, manufactured to high British and European standards.

The Prima Plus fitting has solder pre-integrated within the ring, eliminating the need to manually apply external solder during the jointing process, thus saving time and effort.
Yes, it is suitable for water installations (including drinking water due to WRAS approval) and low-pressure gas installations.
For this fitting, the 1" imperial connection is designed for copper pipe where the outer diameter is approximately 28.24mm. This differs from the nominal 1" measurement.
No, because the solder is integrated into the fitting, you do not need to apply additional flux to the pipe or fitting before heating.
It is manufactured to EN 1254 standard, WRAS approved for drinking water, and has BS Kite Mark approval.
Ensure the pipe and fitting are clean. Apply heat evenly to the fitting body. Once the fitting reaches temperature, the integrated solder will melt and flow around the pipe.
This fitting is approved for low-pressure gas installations. Always consult local regulations and product specifications for suitability for specific high-pressure applications.
The joint may not have been heated sufficiently, or flux/solder may not have reached all parts of the joint. Reheat the joint carefully, ensuring the solder flows completely around the pipe and fitting. If the leak persists, the fitting may be damaged and should be replaced.
Ensure the torch is applying sufficient heat evenly to the fitting. Check that the pipe and fitting surfaces were properly cleaned and that no excess solder from previous attempts is obstructing the flow. Make sure the correct heat source is being used for the size of the fitting.
Verify that you are using the correct size pipe (28mm for one end, 1" imperial/28.24mm for the other). Ensure the pipe end is clean, de-burred, and free of any obstructions or deformation. A slight twisting motion can help insertion.
Setup: Ensure both the 28mm copper pipe end and the 1" imperial pipe end (which measures approximately 28.24mm in diameter) are clean, free from dirt, grease, and oxidation. Gently clean the inside of the fitting's socket if necessary. Insert the pipe fully into the fitting. Apply heat evenly around the fitting using a propane torch. Once the fitting reaches the correct temperature, the integrated solder will melt and flow, creating a strong joint. Remove heat and allow the joint to cool undisturbed.
Compatibility: This fitting is designed for use with 28mm metric copper pipe and 1" imperial copper pipe (with an approximate outer diameter of 28.24mm). It is suitable for use with water and low-pressure gas systems.
Care: Copper fittings require minimal care. Avoid harsh abrasive cleaners that could scratch the surface. Ensure connections are properly made to prevent leaks. Store fittings in a clean, dry environment away from corrosive substances.
