Leak tight sealing is achieved through multiple o-ring seals located in the couplers. Buna-N is standard in brass and Viton® is standard in 316 stainless steel.
Poppet valves with dependable, integral o-ring seals are standard in coupler and plug in double end-shutoff applications. In single end-shutoff applications, the poppet valve is installed in the body half.
Valve guides align valves exactly to the coupler’s valve seat preventing chance of leakage when in a disconnected mode.
Locking mechanisms in bodies provide smooth positive sleeve engagement. A firm grip of the plug portion of the coupling assembly is assured with HOKE’s Xylan®-coated stainless locking tabs.
316 stainless steel springs: all springs are constructed from 316 material.
Gyrolok® nut and ferrule system provides leak-tight end connection.
Keyed sleeves for all sizes
HOKE HQC Series quick couplers are interchangeable with Swagelok®, Parker®, and TOMCO® components of the same style.
