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.
