The Solder Ring Straight Coupling (22mm) is an essential plumbing fitting designed to connect two lengths of 22mm copper pipe in a straight, continuous line. Ideal for domestic and commercial central heating systems, hot and cold water supply networks, and general plumbing installations, this coupling allows installers to effortlessly extend pipe runs or join sections together within a secure, uniform layout.
 
Manufactured from high-quality copper conforming to relevant British Standards (such as BS EN 1254), the fitting features pre-formed rings of lead-free solder embedded directly within each socket. This integrated solder design eliminates the need for manual solder wire application during assembly, ensuring an exact, pre-measured amount of metal is drawn evenly into the joint via capillary action when heated, creating a robust, permanent, and leak-free seal.
 
Engineered for efficient installation by professional plumbers and experienced practitioners, the coupling requires standard pipe cleaning, fluxing, and blowtorch heating to activate the internal solder rings. Whether you are extending central heating pipework, joining sections in a residential water distribution network, or completing a complex plumbing layout, this trade-quality straight coupling delivers dependable structural integrity, excellent corrosion resistance, and long-term hydraulic performance.
