K801 Hydraulic static seals
K801 back-up rings are sealing elements that are generally used behind the o-ring in order to ensure system security and minimize extrusion gaps in many applications. Curved design of K801 provides optimum surface pressure distribution between the o-ring and the counter surface.
Advantages
- Large contact surface prevents O-Ring deformation under high pressure
- High extrusion resistance
- Easy installation
- Can be used at high pressure
- Wide range of dimensions
Area of Application
- Injection molding machines
- Presses
- Excavators
- Agricultural machines
- Valves for hydraulic circuits
