The Prima Classic Compression Elbow 15mm x 1/2 is an essential plumbing component designed for professional installers and DIY enthusiasts looking to create secure 90-degree joints between 15mm pipework and 1/2-inch threaded connections. Offering robust reliability, these brass fittings are WRAS-approved and compliant with EN 1254 standards, making them a safe choice for potable water and gas systems, though users should note that they require precise tightening to avoid overtightening which can deform the olive.

Yes, these fittings are WRAS approved, meaning they have been tested and approved for safety in potable (drinking) water systems.
Yes, but you must use a pipe insert (stiffener) inside the plastic pipe to ensure the compression nut has a rigid surface to grip against.
While the compression fitting creates a metal-to-metal seal, some installers use a small amount of jointing compound on the threads for peace of mind, though it is not strictly required.
Yes, the brass construction is rated for the pressures and temperatures typical of residential central heating systems.
While the brass body is reusable, it is highly recommended to replace the olive whenever the connection is disassembled, as the olive deforms during the initial tightening.
Ensure the pipe is pushed fully into the fitting. Tighten the nut by an additional quarter-turn. If it persists, inspect the olive for deformities.
Check the threads on both the nut and the fitting for debris or cross-threading. Ensure the correct wrench size is being used.
Check that the pipe end is not deformed and that there are no burrs on the cut edge. Use a file to smooth the end of the pipe.
To install, ensure the 15mm pipe is cut square and is free of debris. Slide the compression nut and olive onto the pipe, then insert the pipe fully into the elbow body. Tighten the nut by hand until firm, then use a wrench to tighten by an additional half to three-quarters of a turn. For the 1/2-inch threaded side, use PTFE tape on the threads to ensure a secure, leak-proof connection to your appliance. Regularly inspect joints for any signs of moisture or weeping. If a leak occurs, ensure the pipe is fully seated before attempting to slightly tighten the nut further. Avoid using excessive force, as this can crush the olive and damage the fitting.
