Threadless coupling for leak-free connections

Quick-Lok connectors from Gates Corp., Littleton, Colo.

Quick-Lok connectors from Gates Corp., Littleton, Colo. (gates.com), eliminate hydraulic leaks, thus reducing maintenance, downtime, and warranty claims. The threadless couplers include a hardened-steel stem machined to tight tolerances, along with a double O-ring stem-to-adapter interface. A snap ring in the adapter helps eliminate manifold and port leaks that can be common in other connectors. Once the coupling is connected, it cannot be inadvertently disconnected. Nor will it release under pressure. It also resists side loading and impulse shocks. Standard ports do not need to be modified to accept Quick-Lok connectors, which are available in all common coupling and adapter configurations. The connectors can be used on hydraulic equipment using one and two-wire hoses, as well as industry-standard SAE 100R1 and 100R2 hoses.
