Table of Contents
A one-touch coupler is a quick-connect fluid coupler that allows for easy and rapid connection and disconnection of hoses or pipes with a single action. Suitable for various fluids like air, water, and oil, these couplers minimize fluid leakage due to their internal valves that open and close upon connecting or disconnecting.
They're versatile, used across industries for transferring gases and liquids in plants, chemicals, electronics, food processing, and agriculture, particularly for connecting water spray hoses and sprayers.
Available in sizes 1/4, 3/8, and 1/2, with 3/8 being most common. Selection depends on the material being transferred, with special considerations for items like medicines.
Choose based on water volume, pressure, and the coupler's ability to withstand the intended use. High-pressure couplers, featuring more internal balls and a slide lock, prevent accidental disconnections.
Connect by attaching the male plug to the female socket, with some models locking through rotation. They feature an automatic water stop function via internal ball movement. Periodic maintenance is crucial to address wear and ensure continued proper function.
