The Prima Classic Compression Wallplate Elbow is designed for professional plumbers and DIY enthusiasts who require a robust, secure transition between 22mm pipework and 3/4 inch female threaded fixtures. It provides a highly reliable, leak-free connection for both water and gas systems, offering peace of mind through its WRAS approval for potable water usage. While this fitting offers exceptional durability due to its trade-grade brass construction, it requires precision during installation to ensure the compression olive seats correctly to prevent potential seepage.

Yes, it is fully WRAS approved, making it safe for use in potable water supply lines.
Yes, the trade-grade brass construction is suitable for both water and gas plumbing applications.
The compression side is designed specifically for 22mm diameter pipework.
You will need two adjustable spanners and a pipe cutter or hacksaw to prepare the 22mm pipe.
Compression fittings rely on the olive to create the seal. While not strictly necessary, some professionals use a tiny amount of jointing paste to aid the seat.
It is the European standard that specifies the dimensions and requirements for copper and copper alloy plumbing fittings.
Tighten the compression nut by an additional quarter-turn. If it persists, inspect the olive for damage.
Unscrew the 3/4 inch connection, clean the threads, re-apply high-quality PTFE tape or jointing compound, and reconnect.
Ensure the pipe is fully inserted into the fitting body and the olive is not skewed against the pipe surface.
To install, ensure the 22mm pipe is cut square and deburred to prevent damage to the internal olive. Slide the nut and olive onto the pipe, insert the pipe into the fitting, and hand-tighten the nut. Use two adjustable spanners—one to hold the body of the elbow and one to tighten the nut—by a further three-quarters of a turn. When connecting to the 3/4 inch female threaded side, use PTFE tape or an appropriate thread sealant to ensure a leak-free seal. Regularly inspect the fitting for signs of corrosion or moisture, especially in hidden installations, and avoid using harsh chemical cleaners that may damage the brass finish.
