The 20x30x7 oil seal is typically made from high-quality materials such as Nitrile Butadiene Rubber (NBR), a popular choice due to its excellent resistance to oils and fuels
20x30x7 oil seal. The design incorporates a metal case for added strength and stability, ensuring the seal can withstand the pressures and temperatures encountered in various industrial environments.

Moreover, the rigidity of the metal case ensures better dimensional stability, reducing the risk of deformation under pressure. This is particularly beneficial in dynamic sealing applications where the seal is subjected to continuous movement. The metal casing also improves the seal's performance in situations where there is a significant difference in temperature between the seal and the surrounding environment The metal casing also improves the seal's performance in situations where there is a significant difference in temperature between the seal and the surrounding environment

One of the primary factors influencing the price of oil seals is the cost of raw materials. Oil seals are typically made from a combination of rubber, plastics, and metals, all of which have their own price volatility. For instance, the cost of synthetic rubber can change dramatically based on the price of crude oil, as it is a petroleum-based product. When oil prices rise, manufacturers may face higher production costs, which they often pass on to consumers. Furthermore, geopolitical tensions or natural disasters can disrupt the supply chain, leading to increased raw material costs and, subsequently, higher oil seal prices.
