The Primaflow Endfeed Coupling is designed for professional plumbers and serious DIY enthusiasts who require reliable, leak-free copper piping connections in water and gas installations. These fittings provide a high-integrity, permanent bond through capillary action, though they require proficient soldering skills to ensure a secure joint compared to push-fit alternatives.

Yes, Primaflow endfeed fittings are designed for use with both water and gas systems, provided they are installed according to local building regulations.
No, these are copper endfeed fittings designed specifically for copper pipe. Using them with plastic or PEX piping will result in failure.
Yes, always clean the pipe ends and the inside of the fitting with an abrasive pad to remove oxidation, which ensures the solder bonds correctly.
WRAS approval ensures the materials used in the fitting do not contaminate the water supply, making them safe for drinking water.
No, endfeed fittings create a permanent, soldered joint and must be cut out if you need to alter the plumbing configuration.
Ensure the fitting and pipe are sufficiently clean and that enough flux is applied to facilitate capillary action.
The joint was likely not heated evenly or the solder was applied before the copper reached the correct temperature. Re-clean and re-solder, or cut out and replace the section.
Excessive heating can cause oxidation; use a flame spreader or lower heat settings once the desired temperature is reached.
To install these couplings, start by cutting your 28mm copper pipe square and removing any burrs. Clean the pipe end and the inside of the coupling with a wire brush or abrasive cloth. Apply a thin, even coat of soldering flux to both surfaces. Slide the coupling onto the pipe, apply heat evenly around the fitting with a blowtorch, and introduce solder to the joint until it flows fully around the circumference. After the joint cools, wipe away any flux residue, as active flux can corrode copper over time if left in place. Always ensure you are working in a ventilated area and following all safety precautions for handling open flames.
