• Easy DIY: isolate supply, remove handles, brush away debris, swap the tap cartridge, tighten the 4 mm screw, refit; no need to count splines beyond 20.

Silence that dripping spout with a proven tap cartridge replacement designed for UK two-handle taps. This pair of Replacement Brass inserts uses a Brass Ceramic construction: solid brass bodies and hard-wearing Ceramic Disc seals for smooth action and long service life. Quarter Turn control delivers fast on/off and precise flow without the endless twisting of older washers. Sized for the most common setup: 1/2" BSP threads, 20 Teeth spline, and a 4 mm handle screw. Each Cartridge is purpose-built for its side (hot and cold are not interchangeable). Suitable for kitchen, basin, pillar and sink mixer installations on mains or gravity systems. Compatibility is broad, but taps can look alike. For best results, isolate water, remove your old Tap Cartridge, and compare its dimensions and spline count with the schematic/photo before ordering. If water drips from the end of the spout, these cartridges are the fix; if you see seepage around the tap’s body, replace the spout seals/O-rings instead. DIY-friendly fitting: turn off supply, lift the handle, brush away debris, install the new valves, tighten the 4 mm screw, and refit the cap. The smooth 1/4 Turn feel and clean shut-off will make everyday use a pleasure. Ideal as a reliable mixer tap cartridge and a straightforward tap valve replacement.
