Hydraulic fittings
STAUFF 
Reinforced hoses and accessories
Reinforced hoses provide a safe connection between moving parts of piping systems.
When selecting hose connections, we recommend monitoring the following criteria:
- resistance to medium, pressure and temperature
- bending radius
- external forces and pressure impulses
- external wear
- installation conditions
- range of seals and safety
Material design of fittings: stainless steel, zinc-plated
Connection types
- metric fittings with 24° cone
- metric universal fittings
- metric fittings with 60° cone
- Whitworth thread fittings
- ORFS fittings
- L/S cutting rings
- banjo bolt fittings
- compact crimp fittings
- fittings with flange connection
Basic parameters for hose selection
- permissible pressure
- nominal bore
- ambient temperature
- media compatibility
- selection of fittings
Applications
