Screw Flat Face Coupling
Screw Flat Face Coupling are an essential tool in hydraulic systems for swiftly connecting and disconnecting hoses or tubing without the need for tools. Its flat sealing surface design helps to minimize fluid loss and prevent air from entering the system during connections and disconnections, which is crucial for maintaining the cleanliness and efficiency of hydraulic systems.
Features of Screw Flat Face Coupling
- Screw Flat face coupler is perfect for hydraulic line connection, which can prevent air entering when connect, and prevent leakage when disconnected.
- The plug and sleeve are quenched to withstand damage due to hydraulic and mechanical shocks
- The valve type is flat type, which means only a small amount of fluid is lost when disconnected.
