Market demand significantly influences oil seal prices. In periods of high demand, such as when automotive or aerospace industries experience growth, the price of oil seals can rise. The global push towards electric vehicles (EVs) and advanced machinery can increase the demand for high-performance oil seals, contributing to price variations. Conversely, in times of economic downturn or decline in manufacturing output, demand may decrease, leading to price reductions.
