This 1/2-inch Hose Union Bib Tap is a heavily reinforced exterior brassware fitting designed to provide safe and reliable water access for commercial and domestic outdoor environments. Constructed from premium Dezincification Resistant (DZR) brass, it actively prevents structural degradation and porous leaks caused by aggressive water conditions and prolonged elemental exposure. A critical feature of this unit is the integrated double check valve mechanism, which strictly enforces unidirectional flow to ensure that contaminated wastewater cannot back-siphon into the main potable supply network.

Engineered to withstand rigorous daily operation, the tap manages dynamic system pressures up to 6 bar while maintaining precise flow control. The standard 1/2-inch designation refers directly to the supply line connection size rather than the nut and tail, and it features an industry-standard M30 hose union connection to facilitate rapid attachment of standard exterior hosing. At 105mm in height and weighing 0.285kg, it offers a sturdy, compact profile that guarantees long-lasting performance across demanding site applications.
