Hydraulic Quick Couplings
Offering a wide variety of designs each tailored to a particular application. Based on valving, Hydraulic Quick Couplings generally are either Double Shut-Off or Straight-Thru. Double Shut-Off couplings contain shut-off valves in both halves (coupler and nipple) and are used extensively when loss of fluid is undesirable. Straight-Thru couplings have no valves in either half and are ideal for maximum flow applications.
Used primarily for transfer of hydraulic fluid, and also used with chemicals, water, steam and some gases.
