Cat Pumps 20189 Back up Ring

Product Description:

  • A Back-Up Ring is a rigid, ring-shaped support device used in sealing systems to prevent the extrusion of O-rings or other soft seals under high pressure.

  • Typically made from durable materials such as PTFE (Teflon), nylon, or hard rubber, the back-up ring is installed adjacent to a primary seal in static or dynamic applications to reinforce sealing performance, extend service life, and maintain pressure integrity.

  • Back-up rings are commonly used in hydraulic, pneumatic, and high-pressure fluid systems, especially where pressure surges or large temperature fluctuations occur.

  • Whether in a heavy-duty hydraulic pump or a precision aerospace actuator, the Back-Up Ring plays a critical role in maintaining seal integrity, ensuring optimal performance and minimizing downtime.
