You will need two wrenches: one to hold the fitting body and another to tighten the compression nut. A pipe cutter and deburring tool are recommended for preparing the pipe ends.
It is strongly recommended to use a new olive each time a compression joint is made or remade. Reusing an old olive may result in a poor seal and potential leaks.
WRAS (Water Regulations Advisory Scheme) approval means the product has been inspected and complies with strict water supply regulations in the UK, ensuring it is safe for use with drinking water.
This fitting is approved for water, air, and oil supplies. It is not typically approved or recommended for gas installations, which require specific gas-rated fittings.
While WRAS approved for hot and cold water, specific maximum pressure and temperature ratings depend on the pipe material and overall system design. Consult relevant plumbing standards and the system designer for detailed specifications.
Tighten the nut until it is snug, then use two wrenches to tighten approximately 1-2 full turns. Overtightening can damage the pipe or fitting. If specific torque values are available, follow those recommendations.
Yes, this coupler is suitable for use with both rigid copper pipe and certain types of flexible plastic pipe (e.g., PEX or PB) that are designed for compression fittings, provided they meet the 15mm outer diameter requirement and are compatible with compression olives.
Check if the compression nut is sufficiently tightened. If not, tighten it further. Ensure the pipe ends were clean, round, and free from damage. If the olive has been compressed multiple times, it may need replacing. Disassemble, clean, and reassemble with a new olive if necessary.
Ensure threads on the nut and fitting body are clean and free from debris. Lubricate threads lightly. Make sure the pipe is fully inserted into the fitting.
You may have overtightened the compression nut. This can damage the pipe or the fitting. Disassemble the joint, inspect both components for damage, and replace if necessary. Always use appropriate tools and avoid excessive force.
Verify that you are using the correct size fitting (15mm) for the pipe. Ensure the pipe end is not out of round or damaged. Clean the pipe end.
