The secure hose connection for engine or tank removal! Advantages of the Kent system quick couplings: A safe opening and closing with one hand, as soon as one side is fixed. The design of the "shut-off" valve is a double chamber system, which closes when disconnecting the coupling. (This design enables easy and safe opening of the quick couplings, even under high pressure. Similarly, just as in low pressure applications.) You feel a snap when connecting the couplings, preventing over-tightening or accidental opening. The actions of opening and closing the quick couplings are identical, so that the handling is extremely simple. An ergonomic design guarantees easy handling, yet the space requirement for the couplings is low. Long and safe life of the couplings even with frequent connection and disconnection. In order to protect the fully encapsulated KENT quick coupling system against dirt even after dismantling, sealing the ends with the corresponding white plugs and caps is recommended.
