Durable Plastic Toilet Inlet Valve Kit

A robust, field-proven inlet valve assembly tailored for UK domestic toilet tank refurbishment. Built from glass-fibre reinforced polypropylene for dimensional stability under thermal cycling and prolonged water exposure. Features a dual-stage sealing system: primary needle valve seat plus secondary compression washer interface. Supplied with G1/2 inch BSP male-threaded valve body, adjustable float lever, flat EPDM washer, and corrosion-resistant locking nut. Meets typical UK cistern depth and fill-volume requirements (6–8L per cycle). Installation requires only manual tightening; no sealants, tapes or specialist tools needed.
