A high-pressure hydraulic coupling is a quick-connect or threaded fitting designed to safely connect hydraulic lines under high pressure, typically used in systems operating above 3,000 psi (207 bar) and often reaching up to 10,000 psi (690 bar) or more in ultra-high-pressure applications.
Leak-Free Connection: Designed to maintain a secure, tight seal even under extreme pressure.
Quick-Connect or Threaded:
Quick-connect (push-to-connect) for fast attachment/detachment without tools.
Threaded couplings (like screw-to-connect) for better pressure handling and vibration resistance.
Non-Spill or Flat-Face Options: Prevent fluid loss and air inclusion during connection/disconnection.
Materials: Typically made from hardened steel, stainless steel, or brass, depending on the media and environment.
Locking Mechanisms: Ball-locking or thread-locking designs for secure fitment.
