Brass Extended Stem Concealed Valve Cartridge

Repair leaking concealed shower valves, wall-mounted mixers, and hidden stop cocks effortlessly with our Heavy-Duty Brass Extended Stem Concealed Valve Headwork. Precision-machined from corrosion-resistant solid forged brass, this replacement valve core features an extended splined spindle stem designed to bridge deep wall-embedded plumbing valves out to the finished tile surface.

Equipped with a high-durability rubber sealing washer (or ceramic disc assembly) and a heat-resistant EPDM O-ring seal, this headwork cartridge restores smooth water flow control and prevents dripping, handle slippage, and internal leaks inside wall cavities. Compatible with major concealed stop valve brands, wall-mounted basin/shower mixers, and flush valves across Saudi Arabia and the GCC, it is an essential maintenance spare part for plumbers, facility managers, and home maintenance kits.
