Hunterâs HQ Quick Couplers are innovative, high-value products designed specifically for projects that require quick water access while maintaining in-ground durability and vandal resistance. Our HQs are engineered to endure many years of daily use and are designed for maximum reliability. With heavy-duty red brass and stainless steel construction, all HQs feature our TuffTop⢠spring-loaded locking or non-locking covers. The unique WingThing⢠models feature anti-rotation stabilisers for added vandal-resistance and operational durability. One-piece and two-piece models are available. The two-piece body design allows field maintenance of the valveâs upper seal without depressurising the irrigation system. All locking cover models have a purple cover option, making them suitable for use on reclaimed water projects. All models are configured for retro-compatibility with the popular brands installed over the years.
