Parker 59 Series threaded hydraulic couplers are rated up to 6000 psi and connect with 59 Series nipples. Parker 59 Series quick couplings are the premiere screw to connect coupling for high impulse, high pressure applications.

The rugged Acme threads are resistant to damage and have a double start feature to quickly align the threads, saving time and eliminating frustration. As few as two and one half sleeve rotations will complete a full 59 Series connection. The bright orange O-ring is concealed by the sleeve and you can also feel when the coupler and nipple are fully mated, giving both a visual and tactile confirmation of a secure connection.

Engineered to perform, the 59 Series heavy duty coupling was designed with an internal bearing to reduce hose twist and ease the difficulty of connecting fluid lines while under pressure. These rugged quick connect fittings are built with high strength materials and are highly impulse resistant. The coupler and nipple have non-spill stainless steel valves and can be connected under residual pressure up to 5000 psi and disconnected under residual pressure up to 2500 psi.
