K801

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
