APPLICATIONS:

297 series is the ultimate solution and most popular for hydraulic circuit applications subject to high pressure impulses, and circuits which experience high residual or
trapped pressure in a line. Thread-to-connect design eliminates premature wear or brinelling associated with locking ball designs subjected to high impulse pressures.The internal valve allows connection and disconnection with high residual pressures. Flat face design avoids loss of hydraulic fluid during connection/ disconnection.
Flat face design is easly to clean, limiting contamination into the circuit.



- High working pressures: 40-60 MPa/5800-8700 psi range based on size.
- Thread coupling system eliminates brinelling, premature leakage.
- Connect/disconnect under residual pressure up to 25 MPa/3625 psi.
- Valve limits fluid movement during connection avoiding damage to other elements of circuit.
- Low connection force required.
- Excavators w/auxiliary line for attachments: thumbs, grapples, hammers, and compactors/hopaks.
- Oil Field, well head drives, porta-power.
- Cranes, drilling machines, all large equipment needing junction points in circuit.
- All construction equipment applications with higher pressure
requirements or issues of connecting/ disconnecting tool attachments under residual pressure.
- Eliminates brinelling, reduces leakage.
- Save time changing tools.
