Easy operation with just a push to connect and a pull to disconnect! Made of stainless steel (316 series)! Non-spill coupling with no liquid dripping during attachment and detachment!
【Non-Spill】 The flat face structure prevents liquid dripping, air ingestion, and foreign matter contamination during attachment and detachment. It ensures the safety of the operator and keeps the surrounding environment clean. 【Compact Design】 With an ergonomic design for ease of use, it is compact and can be installed in various locations without restriction. 【Easy Operation】 Simple operation with just a push to connect (automatic ball lock system) and a pull to disconnect. 【Excellent Mechanical Strength】 The part of the plug that inserts into the socket (guide mechanism) is long, providing sufficient strength against vibrations and other forces. 【Secure Lock】 A large number of locking balls are arranged to create a reliable and robust locking system. 【KES Sealing】 If the connection part has a G-thread, easy sealing is achieved with KES sealing (see detailed information).
