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.

Key Features

  • Solid Forged Brass Construction: Resistant to dezincification, hard water corrosion, mineral buildup, and thermal expansion fatigue for years of drip-free service.

  • Extended Stem Shaft: Extra-long splined shaft reaches deep concealed wall valves without needing hazardous wall demolition or tile removal.

  • Precision Splined Handle Fit: Standard multi-tooth splined tip ensures a tight, non-slip engagement with decorative faucet handles, knobs, and lever trim kits.

  • Dual Leak-Proof Seals: Features a durable lower rubber compression washer and upper EPDM rubber O-ring to guarantee 100% watertight sealing under high city water pressure.

  • Universal Threaded Mounting: Standard ISO metric/BSP male threads allow direct drop-in replacement into standard brass concealed stop valve bodies.
