CAT 1982643 Backup Ring
CAT 1982643 Backup Ring
Product Description :
- A backup ring is a mechanical component used in sealing systems to protect primary seals, such as O-rings, from damage due to pressure, extrusion, or wear.
- It is typically made from materials like metal, plastic, or elastomers and is placed behind the primary sealing element to provide additional strength and support in high-pressure applications.
- It is a type of sealing component used in conjunction with elastomeric seals, such as O-rings, to enhance their performance in high-pressure or high-temperature applications.
- They are typically made from rigid materials such as polytetrafluoroethylene (PTFE), polyurethane, or other durable plastics.
- This rigidity helps prevent deformation under pressure.
- They usually have a circular shape, similar to O-rings, but are thicker and designed to fit in a groove adjacent to the primary seal.
- A Backup Ring is a protective sealing component used alongside O-rings to prevent extrusion and extend seal life in high-pressure applications. Typically made from durable materials such as PTFE, nylon, or elastomers, it provides structural support to the O-ring by filling the extrusion gap and maintaining shape under pressure. Backup rings are especially effective in dynamic and static sealing systems where high temperature, pressure, or chemical exposure may compromise sealing performance.
