Flat Face Connect Under Pressure Hydraulic Couplers Stucchi ISO 16028

Finding it almost impossible to do up attachment line couplers? Here's the answer!

The "Male" “APM” Flat Face and the Female A-HD Series Flat Face couplings are the solution for the manual connection with high residual pressure in the circuit.

The male coupling has a triple valve system: double internal pressure release valve and the flat face valve.

This system easily allows the connection of couplings with the presence of high internal residual pressure on the male side without fluid loss.
Based on this main feature, “APM” male couplings are the ideal solution to hydraulic applications where there is the requirement to connect the circuit with internal residual pressure.

The APM series conform to ISO 16028

Used extensively on all manner of Hydraulic machines, these flat face couplers are the most common flat face size for Australian used machines . These are interchangeable, compatible with common ISO 16028 flat face couplers. You can choose to use just the male half, female half or both. Often only a male half is required.

Theoretical calculation of connect force with residual pressure:

Benefits

• Easy connection with male side under residual pressure (female side to drain) thanks to the internal valve.
• Flat face is easy to clean, reducing the inclusion of contamination inside the hydraulic circuit.
• Minimal fluid spillage during disconnection, reducing fluid spillage to the environment.
• Minimal air inclusion during connection.
• Internal valve design creates minimal pressure drop, maintaining circuit efficiency in the system.
• Male body black zinc plated for identification
• The modular design allows flexibility with a wide range of configurations.
• Good resistance to pressure impulses.
• Compact slim design.
• Safe and simple to use.

• Before to connect, clean the mating surface of the couplings to avoid dirt inclusion in the circuit.
• To connect push the male half towards the female half or vice versa.
• After connection turn the external sleeve (on the female Half) to engage safety lock function to prevent accidental disconnection.
• To disconnect turn the external sleeve on the female half until the sleeve lock notch match the safety lock ball and push back the sleeve.
