4H-6730: O RING
Chart
Description
O-rings are used primarily as axial or radial seals for static applications to prevent leaks and contamination.
Features
Cat® O-ring seals are made of materials that correspond to the oil, temperature, and pressure in Cat® engines and machines. These materials are resistant to wear and extrusion and provide excellent resistance to compression and deformation of seals. In addition, certain Cat® O-rings are PTFE coated to minimize seal distortion and cutting during seal installation.
Our O-ring sizes follow tight tolerances to ensure that they fit properly into the seal groove with the necessary seal compression.
With more than 2,500 O-rings in different sizes and materials, Cat® O-rings are the best solution for your Cat and other mobile device O-ring needs.
