Backup Rings
Backup Rings are anti-extrusion sealing components used in conjunction with O-Rings to prevent seal deformation under high pressure. They are essential in applications where O-Rings are exposed to elevated pressures, large clearances, or dynamic motion.
Our Backup Rings are designed for industrial hydraulic and pneumatic systems, improving sealing reliability and extending O-Ring service life.
What Are Backup Rings?
Backup Rings are rigid or semi-rigid sealing elements installed adjacent to O-Rings in a sealing groove. Their primary function is to support the O-Ring and prevent extrusion into the clearance gap when subjected to high pressure.
From an engineering standpoint, backup rings are critical for maintaining sealing integrity in high-pressure and dynamic applications where standard O-Rings alone may fail.
Types of Backup Rings
- Solid (Endless) Backup Rings
- Split Backup Rings (Scarf-cut or spiral)
- Single backup ring configurations
- Double backup ring configurations for bi-directional pressure
The choice between solid and split backup rings depends on groove design, installation constraints, and pressure direction.
Sizes & Specifications
Backup Rings are available in standard O-Ring size equivalents as well as custom dimensions to match specific sealing grooves.
- Compatible with AS568 O-Ring sizes
- Metric size options available
- Single or dual ring configurations
- Custom dimensions upon request
Available Materials & Options
- PTFE (Virgin or Filled) – Low friction, chemical resistance
- PTFE Filled (Glass / Carbon / Bronze) – Enhanced wear resistance
- PEEK – High strength for extreme pressure
- Nylon (PA) – Cost-effective, moderate pressure applications
Material selection is based on pressure, temperature, chemical exposure, and dynamic or static sealing conditions.
