The Solder Ring Reducing Tee (28mm x 22mm x 15mm) is an essential plumbing fitting designed to branch a main 28mm copper pipeline down into two smaller secondary lines measuring 22mm and 15mm. Ideal for domestic and commercial central heating networks, hot and cold water supply systems, and complex plumbing layouts, this multi-size junction allows installers to efficiently split fluid flows and adapt pipe diameters within a single, compact fitting.
 
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 tee requires standard pipe cleaning, fluxing, and blowtorch heating to activate the internal solder rings. Whether you are re-routing central heating pipes, installing a complex bathroom manifold, or expanding a domestic water system, this trade-quality reducing tee delivers dependable structural integrity, excellent corrosion resistance, and long-term hydraulic performance.
