This high-quality 22mm x 1″ Female Brass Compression Straight Adaptor connects standard 22mm copper or plastic piping to a 1″ male threaded fitting. Specifically, it provides a durable, secure, and completely leak-free transition between pipework and appliances or fixtures. Furthermore, thanks to the reliable compression ring mechanism, you significantly speed up installation by eliminating the need for heat, flux, or solder on site.
Therefore, this Compression Straight Adaptor – 22mm x 1″ Female works perfectly for hot and cold domestic water systems, as well as central heating applications. Additionally, it easily handles demanding environments, ensuring a robust mechanical joint that safely withstands standard domestic pressures and temperatures.
The fitting features a solid brass construction, providing excellent resistance to corrosion, temperature fluctuations, and mechanical stress. Moreover, the material is highly durable and designed for continuous operation over decades. As a result, this robust build makes it fully reliable for long-term residential, commercial, and industrial plumbing installations.
Key Features & Benefits:
-
Heat-Free Installation: The mechanical compression design allows for secure tightening using just standard spanners. Consequently, you achieve fast, safe installation in tight spaces without the need for a blowtorch or hot works permits.
-
Versatile Compatibility: The fitting seamlessly joins 22mm pipe to a standard 1″ BSP threaded connection. For example, it perfectly adapts pipework to radiator valves, tap tails, or female iron fittings, offering maximum flexibility across your system.
-
Durable Brass Construction: Manufactured from heavy-duty solid brass. Importantly, it ensures excellent structural integrity and guarantees full protection against leaks within the heating or water installation.
-
Fully Demountable: The compression joint can be easily undone and adjusted if required. In particular, this provides an excellent advantage, effectively simplifying future system maintenance or alterations without the need to cut away existing pipework.
