•t Leak tight sealing is achieved through multiple
o-ring seals located in the couplers. Viton® is
standard.
•t Poppet valves with dependable, integral o-ring
seals are standard in coupler and plug in doubleend-shutoff applications. In single-end-shutoff
applications the poppet valve is installed in the
body half.
•t Valve guides align valves exactly to the coupler’s
valve seat preventing chance of leakage when in a
disconnected mode.
•t 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.
