  • What are pressure couplers?

    Pressure couplers are integral components of any hydraulic system. They connect two pieces of equipment under pressure, allowing fluid to flow without additional fittings or connections.

  • What are hydraulic couplers called that connect under pressure?

    Connect under pressure hydraulic couplers are non-spill couplings that can both disconnect and connect pressurized lines.

  • What coupler sealing is most used for high-pressure hydraulic fittings?

    The most common type of sealing used for high-pressure hydraulic fittings is O-ring face seal (ORFS) technology. An elastomeric O-ring is compressed between the male and female halves to create a secure connection without leakage. ORFS couplings are designed to resist pressures of up to 10,000 psi and temperatures from -54°C through +204°C.

  • How do you release pressure from a hydraulic coupler?

    Releasing pressure from a hydraulic coupler requires careful attention as it involves working with potentially hazardous fluids at very high pressures. The first step is disconnecting the coupling by pushing the sleeve while pulling back on the plug until it releases entirely from its socket. Once disconnected, you must depressurize both sides before opening either side fully so that all residual pressure has been released safely away from personnel or equipment nearby.

  • How do you connect couplers?

    Connecting couplers correctly ensures proper operation and prevents leaks or other issues. First, make sure both halves are perfectly aligned before pushing them together until they click into place securely. Then check for any signs of leakage around the joint. Finally, always use appropriate safety gear such as gloves and eye protection when handling these components due to their potential hazards if not handled properly.
