Danfoss Hansen® FD83 Series Coupling
Thermal Management
Danfoss Hansen's FD83 coupling is designed for fluid transfer and electronics cooling applications where full flow, fluid compatibility, and safety are essential. The FD83 identical halves include two interlock features to eliminate spills and ensure maximum safety. Valves cannot be opened until the coupling halves are mated and coupling halves cannot be disconnected until both halves are closed.
NEW! The FD83 coupling is now available in size 2”.
Product Features
- Dual interlock safety feature eliminates accidental opening of coupling when disconnected with the use of a patented locking pin design and lever handle
- Design provides reliable performance and no spillage during maintenance or service
- Standard seal material: EPDM, additional material available on request
- Standard body material: 303 stainless steel
- Full flow coupling
- Identical coupling halves
- Maintenance and service friendly
- 303 stainless steel material provides broad fluid compatibility
- Wide range of terminal end options
- Operation temperature range: -3°C min (26.6°F), 60°C max (140°F)*
*For reference only, based on Danfoss recommended temperatures.

Flow Data
Test Fluid: Water at 70°F
A graphical representation of pressure drop versus flow rate is provided. The graph shows pressure drop in PSI and bar on the Y-axis and flow rate in l/min and gpm on the X-axis. Multiple lines represent different flow rates and their corresponding pressure drops.
