for Caterpillar Seal O Ring 7m-9909 7m9909 8n2410 8n-2410
Caterpillar's O-ring models are extremely meticulous in material selection, using materials that perfectly match the oil, temperature, and pressure in the engine and machine. Taking the common nitrile rubber (NBR) as an example, it has good resistance to mineral oil, lubricating oil, etc., and can maintain stable physical properties in the temperature range of -40 ℃ to 120 ℃. In the high-temperature and high-pressure working environment of Caterpillar engines, O-rings made of nitrile rubber are not easily corroded by oil and always maintain good elasticity and sealing performance. Moreover, these materials have excellent wear and extrusion resistance, and will not easily wear or deform under frequent relative motion and strong pressure of mechanical components, greatly extending their service life. At the same time, they also have excellent resistance to compression deformation, and can quickly recover to their original state even after being compressed for a long time,
