Fluidmaster AirGap 6000 1/2" Brass Shank Side Entry Fill Valve
The Fluidmaster AirGap 6000 (FTB14202) is a high-performance, water-saving side-entry cistern fill valve engineered with a robust 1/2" heavy-duty brass threaded shank. Featuring innovative delayed-fill technology, it prevents the cistern from refilling until the flush valve has fully closed, saving up to 1 litre of water per flush cycle. Fully compliant with BS1212-4 and BS6920 standards, it delivers exceptionally quiet, anti-siphon performance across both high and low water pressure systems.
