Description
O-rings are used for static sealing and some dynamic applications.
Features
Cat® O-rings are made from materials compatible with the fluids, temperatures and pressures in Cat engines and machines. These materials resist wear and extrusion, giving the seals excellent compression set resistance. In addition, some Cat O-rings are coated with PTFE to minimize seal twisting and cutting during 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.
With more than 2500 different sizes and materials of O-rings, Cat O-rings are the best solution for the O-ring needs of your Cat and other mobile equipment.
Cat sealing systems prevent leaks and contamination of more expensive parts. Genuine Cat seals protect your investment.
Applications
O-rings are used in many static and dynamic joints in Cat machines and engines.
Specifications
| Material | VMQ – Silicone Rubber |
|---|---|
| Material Description | Silicone provides excellent performance over a wide temperature range (from very low to moderately high temperatures), performs exceptionally in air applications and is also compatible with engine oil. It has limited strength and abrasion/cut resistance, so it is best used in low-pressure applications. Silicone must not be used with diesel fuel, coolant/urea, hydraulic oil, automatic transmission fluid or biodiesel. |
| Coating | None |
