Oil seals are generally constructed from materials that can withstand the specific chemical properties of the lubricant they are sealing. Common materials include rubber, silicone, and various elastomers. The design of an oil seal often incorporates a lip that rolls against a shaft or surface, creating a dynamic seal that can accommodate movement while maintaining its sealing capabilities.

The material of lock stitch sewing machine needles is another factor to consider. Most needles are made from high-quality steel, often coated with chrome or nickel to enhance durability and reduce friction. These coatings enable smoother sewing, especially when working with dense or heavy materials. Using the right needle material can significantly impact the lifespan of both the needle and the sewing machine, as well as reduce the likelihood of needle breakage, hence preventing potentially costly machine repairs.
