The Hansen HK Two-Way Shut-Off Couplers - Female NPT End Connection Plugs seal both ends of line when coupling is disconnected. Spring actuated valves in both socket and plug provide immediate seal against escape of gas or liquid. Couplings can be used for compressed air, hydraulic fluid, liquids, paints, steam, refrigerants, gases, vacuum (limited), and oxygen. LP Gas and Vacuum Service is not recommended for 4-HK, 6-HK, and 8-HK Series Couplers. Any plug and socket from the same series, regardless of end connections, fit together to make a coupling assembly.
