The hose faucet drip filter is designed specifically for drip watering systems. It removes debris from the water supply and minimizes clogging in drip emitters and micro-sprinklers. The inlet is standard 3/4-in. female hose thread with swivel which threads onto a hose faucet. The outlet is standard male hose thread to which you can attach a garden hose or a drip hose faucet adapter. The 150-mesh stainless-steel filter ensures removal of even very fine particles. It uses an angle geometry which makes cleaning the filter as simple as removing the cap, turning the water on to flush out debris, and then replacing the cap. For drip applications, use the filter in combination with a 25 PSI hose thread pressure regulator (sold separately). For outdoor use with cold water only.
