Hunter Check Valves - 1/4 Female Male

Hunter in-line check valves prevent reverse flow and back-siphoning in irrigation systems, protecting the water supply from contamination and preventing emitter drain-back that can dislodge drip stakes and wash away growing media. The 1/2" female-to-male configuration fits standard drip emitter fittings for direct in-line installation in drip and micro-irrigation systems.
