The Solder Ring Fitting Reducer (22mm x 15mm) is an essential plumbing component designed to neatly step down a 22mm copper pipeline to a smaller 15mm section within a compact footprint. Ideal for domestic and commercial central heating systems, hot and cold water networks, and general plumbing installations, this reducer allows installers to smoothly adapt pipe diameters without requiring bulky transition assemblies.
 
Manufactured from high-grade copper conforming to relevant British Standards (such as BS EN 1254), the fitting features a pre-formed ring of lead-free solder embedded directly within the 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 reducer requires standard pipe cleaning, fluxing, and blowtorch heating to activate the internal solder rings. Whether you are scaling down central heating pipework, adapting a hot water supply run, or completing a complex plumbing layout, this trade-quality fitting reducer delivers dependable structural integrity, excellent corrosion resistance, and long-term hydraulic performance.
