This 28mm x 15mm Endfeed Reducing Coupler is designed to connect a 28mm copper pipe directly to a 15mm copper pipe in domestic and commercial plumbing and heating systems.
Manufactured from high-grade, lightweight copper, it features capillary sockets at both ends for a clean, permanent joint using soft or hard solder with flux. Ideal for hot and cold water supply lines as well as central heating pipework, it provides a compact, seamless, and leak-free inline reduction between different pipe sizes.
