This 15mm x 10mm Endfeed Reducing Coupler is engineered to connect a 15mm copper pipe directly to a 10mm copper pipe in domestic plumbing and central heating systems.
Manufactured from high-grade, lightweight copper, it features precise capillary sockets on both ends for a clean, solder-ringed or wire-solder connection using flux. Ideal for hot and cold water runs, microbore heating systems, or radiator tail connections, it provides a compact, seamless, and leak-free inline reduction between pipe sizes.
