Hansen 5600 SeriesStainless Steel Couplings
Danfoss Hansen 5600 Series stainless steel quick disconnect couplings deliver ISO 7241-1 Series A interchange with rugged poppet-style performance and strong corrosion resistance for demanding hydraulic and fluid transfer applications.
ISO-A stainless hydraulic couplings
The Hansen 5600 Series stainless steel family is built for hydraulic and fluid transfer service where ISO 7241-1 Series A interchange, self-sealing valving, and corrosion resistance are all important. The catalog positions this series for agriculture, construction, steel mills, plant manufacturing, and vehicle-service environments.
Key Features
ISO 7241-1 Series A
The 5600 stainless family uses ISO 7241-1 Series A interchange, making it suitable for hydraulic systems that need established A-profile compatibility.
303 Stainless Construction
Standard 303 stainless steel construction supports excellent corrosion resistance in tough operating environments compared with standard carbon steel couplings.
Self-Sealing Poppet Valves
The self-sealing poppet valve design is called out in the catalog for excellent high- and low-pressure sealing across the active body sizes in this series.
Pressure drop versus flow
The 5600 Series stainless steel flow data is based on hydraulic oil viscosity of 30 cSt at 40°C / 104°F. The active stainless body sizes in this family are positioned for rugged hydraulic and fluid transfer service with the same ISO 7241-1 Series A profile.
- Test fluid: Hydraulic oil viscosity 30 cSt at 40°C / 104°F
- Active body sizes represented here: 5/8, 3/4, and 1 inch
- Rated flow range: 45 to 189 lpm (12 to 50 gpm) depending on body size
- Self-sealing poppet valving supports clean hydraulic service with strong pressure sealing
Common 5600 stainless applications
The stainless 5600 Series is commonly used where hydraulic performance and corrosion resistance need to live together in the same coupling family.
- Hydraulic and fluid transfer
- Agricultural equipment
- Construction equipment
- Steel mills
- Plant manufacturing and processing equipment
- Dump, snow plow, and maintenance vehicles
