Brass Compression Wallplate Elbow Bright Chrome Plated CxFI 15mm x 1/2" is used to make a 90deg wall mounted connection between copper pipes. It requires no special tools or soldering to install, just tighten with a spanner. It creates a mechanical joint by compressing the ring onto the tube. It can be used in hot or cold water applications as well as heating and low pressure gas installations. The joint can be made on wet pipe work. The chrome plating provides a more aesthetically pleasing finish.
