TWO WAY CHECK VALVE COUPLINGS

 
These are designed for connecting hydraulic lines. They are also extensively used where a variety of other fluids are involved. They are made to withstand pressure from 800 to 10000 PSI depending upon size and material. They contain valves in both the coupler and adaptor to prevent loss of fluid when the parts are disconnected.
