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.




Another important benefit of under-door air stoppers is sound insulation. The gaps beneath doors can allow noise to travel freely from room to room, leading to disturbances in peace and quiet. By effectively sealing these spaces, air stoppers can significantly reduce noise transfer, creating a more serene living environment. This is particularly advantageous in shared living situations, such as apartments or homes with multiple family members, where privacy and tranquility are valuable commodities.
