Application & Function
Back-up Rings serve as supporting elements with rectangular cross-section, preventing extrusion of elastomeric sealing elements into sealing gaps during high-pressure applications. Installed alongside O-Rings in static applications, they provide reliable performance across various operating conditions.
Application Scenarios
- High-pressure hydraulic systems with O-Rings
- Applications using low-hardness O-Ring materials
- Compensation for radial sealing gaps
- Internal and external sealing applications
- Reciprocating and rotating movements
- Systems with large temperature fluctuations
- Static and dynamic industrial applications
