Lip seals stop lubricants, oils, or other fluids from leaking and keep out dirt, dust, or moisture. These are commonly used in cars, factories, and machines to help things run smoothly, make equipment last longer, and need less maintenance. Their design lets them work at high speeds, with different temperatures, and under pressure changes, which makes them important for sealing. https://goodrichgasket.com/metallic-lip-seals
