Description
Cat® seals are used for static sealing and some dynamic applications.
Cat® seals and O-rings are made from materials compatible with the fluids, temperatures and pressures in Cat engines and machines.
These materials are resistant to wear and extrusion and provide the seal with outstanding resistance to compression set.
In addition, some Cat O-rings are also coated with PTFE to minimize seal twisting and cutting during seal installation.
Our O-rings are dimensioned to strictly follow tight tolerances, ensuring they are properly seated in the seal groove with the right seal compression.
Available in more than 2500 different sizes and materials, Cat O-rings are an excellent solution for your O-ring needs on Cat and other mobile equipment.
Applications
Cat® seals and seal rings are widely used in a variety of sealing applications on Cat machines.
Cat sealing systems prevent leaks and contamination of more expensive parts.
Genuine Cat seals properly protect your investment. Refer to your Operation and Maintenance Manual or contact MECHSC for more information.
