What about fluid connectors JR?
The JR profile is a static axial seal for hydraulic applications. DIN3869 defines the standard sizes range.
Minimal mechanical deformation of the cross section even in high pressure that enables a good sealing for a very long time.
ADVANTAGES
- No twisting in the groove
- No relative movements during pressure cycles
- High leak tightness compared to metal/metal sealing
- Injection molding machines
- Machine tools
- Excavators
- Agriculture machinery
- Valves for hydraulic circuits
