  • When disconnecting
    both socket and plug are sealed by automatic shut off valves instantly.
  • When connecting
    automatic shut off valves of socket and plug open and seal by O-ring with Backup-ring.
  • CHP04 and CHP06 are interchangeable as well as CHP10 and CHP12.
  • The rest of combinations for different sizes are not interchangeable.
*Putting dust covers on socket and plug under disconnection is recommendable.
*Fluid can flow from both socket and plug.
Caution
Do not connect or disconnect couplings under pressure as well as under residual pressure.
Do not apply pressure on socket or plug under disconnected. This may cause valve to be blown out.
Do not hit top of valves with hammer or other tools.This may cause leakage or malfunction.
Do not use for water-glycol fluid which damages to coupling's plating.
For hydraulic fluid use , keep its flow rate less than 8m/s.
