The ALS Hardware Capillary CxFI Reducing Elbow is a -grade copper plumbing fitting engineered to create a secure, leak-free 90-degree turn while transitioning and enlarging a soldered copper pipe connection directly to a larger standard male threaded fixture. It features a precision-formed capillary socket (C) on one end for a smooth solder joint onto a 15mm copper pipe, alongside a heavy-duty Female Iron BSP thread (FI) on the adjacent end for securing threaded 3/4″ brass fittings, inline valves, or tap assemblies. Built to withstand high hydraulic pressures and intense thermal stress, this durable adapter elbow is ideal for tight spaces in hot and cold residential water infrastructure, commercial installations, and demanding industrial pipeline layouts.
