A 15 x 8mm compression fit reducing coupling is a reliable plumbing fitting designed to connect a 15mm pipe directly to an 8mm pipe in a straight line without the need for any soldering.
Installation is quick and tool-friendly, requiring only standard spanners to tighten the nuts, which securely compresses the internal olives to create a tight, watertight transition between the two different pipe diameters.
It is ideal for altering plumbing layouts, adapting standard water supply or microbore lines to smaller specialized branch pipes or instrumentation in tight spaces, and working effectively with copper, brass, plastic, and other compatible piping materials.
