This 15mm x 8mm Endfeed Reducing Coupler is engineered to connect a 15mm copper pipe directly to an 8mm copper pipe in a continuous, inline run for domestic plumbing and microbore heating systems.
Manufactured from high-grade, lightweight copper, it features precise capillary sockets on both ends (15mm on one end and 8mm on the other) with an internal step to ensure correct pipe positioning during soldering. Ideal for stepping down main supply lines to small-diameter microbore feeds for radiators, oil lines, or specialty water outlets, it delivers a compact, low-resistance, and leak-free reduced joint.
