15mm x 3/8″ Flat Face Isolating Valve – Service Valve for Tap Flexis

15mm x 3/8″ Flat Face Isolating Valve – Service Valve for Tap Flexis

• 15mm Compression fitting to copper/plastic one end
• 3/8″ flat face BSP thread (measures approx 16mm) the other end
• Ideal for screwing monobloc tap flexis straight onto the end

Most plumbers/DIY’ers usually remove the nut and olive from a standard isolation valve and screw the flexi on. This is not the correct way to do this! Removing the olive reveals a sharp bevelled edge that can easily split the washer if over tightened, causing a leak

Details

The 15mm x 3/8″ Flat Face Isolating Valve is a specialized service valve designed for modern and European-style taps that utilize 3/8-inch flexible tails. Specifically, the flat-face design provides a broad, smooth mating surface that prevents the small rubber washers inside 3/8″ hoses from being sliced or pinched. This valve connects a standard 15mm pipe to a 3/8-inch BSP male outlet. Furthermore, the integrated ball valve provides a quick, localized water shut-off. Consequently, it is the safest choice for installing premium taps with delicate 3/8″ connections.

Installing a high-end European tap often reveals a frustrating compatibility issue that leads to immediate leaks. Specifically, 3/8″ flexible hoses have very small rubber washers that are easily destroyed by the sharp, tapered edges of standard isolating valves. If the edge of the valve is too thin, it acts like a knife, cutting the washer as you tighten the nut. Moreover, finding a valve that adapts 15mm pipe to 3/8″ and offers a safe sealing surface can be a struggle. However, this Flat Face Service Valve eliminates this struggle entirely. Because the outlet face is perfectly flat and wide, it supports the entire washer, ensuring a watertight seal without the need for excessive force. Therefore, you protect your expensive tap hoses and achieve a leak-free installation on the first try.
