Whether you need to prevent leaks, remove contaminants, control pressure, or reduce friction,   auto oil seal  manufacturer HONGLEI's mission is to help you find the right sealing solution for your specific application requirements and business needs. Seals typically consist of three basic components: a sealing element, a metal housing and a spring. The purpose of the sealing element is to stop the leakage of fluid between the shaft and the housing. We must select all materials according to the environment in which the oil seal will work. Choice of materials There are many materials that can be used to produce rubber sealants. Which one we should choose depends on the application of the product. It requires us to know the environment and requirements for its use. And it is necessary to have a good understanding of the various properties of the material at the same time. In addition to the general requirements for the seal material, the following conditions should also be noted. (a)

Temperature Low temperatures can cause the lip of a polyurethane or rubber seal to freeze and become brittle and brittle, reducing elasticity and causing leakage, or even the entire seal to become hard and brittle. High temperatures can cause the seal to expand and soften, resulting in a rapid increase in frictional resistance to seal movement and a reduction in pressure-bearing capacity. Polyurethane or rubber seals are recommended for a continuous ope
