Hansen FD72 / FD76 Series
Agricultural Couplings
Danfoss Hansen FD72 and FD76 Series agricultural quick disconnect couplings are built for hydraulic circuits where connection under pressure, dependable poppet sealing, and rugged 3,000 psi field performance matter.
Connect-under-pressure agricultural couplings
FD72 / FD76 agricultural quick disconnect couplings are designed for hydraulic circuits where connection under pressure, self-sealing poppet valving, and dependable 3,000 psi service all matter. FD72 incorporates the special valving that allows connection to a matching FD76 male half under pressure while maintaining the rugged sealing behavior expected in agricultural hydraulic service.
Product Features
Connection Under Pressure
FD72 incorporates special valving that allows the female half to connect to a matching FD76 male half under pressure.
Poppet Valve Sealing
Self-sealing poppet valve construction supports dependable shutoff and rugged hydraulic handling in agricultural service.
3,000 PSI Performance
The series is built for agricultural circuits that need durable 3,000 psi field performance and repeatable daily connection cycles.
FD72 / FD76 operating profile
| Body Size | Max Operating Pressure | Min Burst Pressure | Vacuum | Rated Flow | Air Inclusion | Fluid Loss |
|---|---|---|---|---|---|---|
| 5/8 | 207 bar / 3,000 psi | 827 bar / 12,000 psi | 28 in./Hg | 61 lpm / 16 gpm | 2.8 cc max. | 2.8 cc max. |
Using FD72 with FD76 under pressure
- FD72 uses special valving that allows connection to a matching FD76 male half under pressure.
- The equipment control valve is typically actuated to open flow and help equalize pressure during connection.
- Once fully engaged, the poppet-style design supports dependable shutoff in normal hydraulic service.
Typical FD72 / FD76 use cases
- Agricultural tractor hydraulics
- Implement connections with residual pressure concerns
- Hydraulic service points requiring poppet-style shutoff
- Field-maintained agricultural coupling replacement
