This 12mm Endfeed Straight Coupler is engineered to join two lengths of 12mm copper pipe in a continuous, inline run for small-diameter domestic plumbing and heating systems.
Manufactured from high-grade, lightweight copper, it features precise capillary sockets on both ends with a central internal stop to ensure correct pipe depth during soldering. Ideal for microbore heating feeds, hot and cold water supply lines, and gas installations, it provides a compact, low-resistance, and leak-free joint built for long-term reliability.
