Caterpillar FKM (75) O-Ring (6V3831) 6V-3831 are mainly used as axial or radial seals to prevent leakage and contamination.

Characteristics.
• Cat® O-rings are made from materials that are compatible with the fluids, temperatures, and pressures used in Cat® engines and machines. The materials have high resistance to wear and deformation and provide excellent resistance to compression. In addition, some Cat O-rings are coated with polyurethane to increase resistance to twisting and damage during installation.
The o-rings are dimensioned to close tolerances to ensure that the seating grooves are exactly matched to the required level of o-ring compression.

Available in over 2,500 sizes and materials, Cat O-rings are the best solution for Cat and other mobile equipment that requires O-rings.

The Cat® sealing system uses robust design, testing and validation.
