This 28mm x 15mm Compression Fit Reducing Set is engineered to adapt a standard 28mm compression socket down to receive a 15mm copper pipe without replacing the parent fitting.
Manufactured from high-grade brass, the set consists of a specially shaped 28mm to 15mm reducing bush and a matching 15mm olive. It inserts directly into any standard 28mm compression fitting body, allowing the original 28mm compression nut to compress the assembly onto a 15mm copper pipe. Ideal for significant step-down pipework reductions in plant rooms, heating systems, and water distribution mains where space is limited and heat-free installation is required, it provides a simple, robust, and re-serviceable watertight joint.
