Oil seals are commonly made from materials such as rubber, silicone, or polyurethane, with each material offering different properties and advantages. Rubber seals are flexible and cost-effective, making them suitable for a wide range of applications. Silicone seals offer high temperature resistance and chemical compatibility, while polyurethane seals are durable and abrasion-resistant.


The mechanical seal is used in a pump, mixer and other mechanical engineering scenarios to contain the fluid within a vessel where a shaft rotates through a stationary (or rotating) housing.
Installing an oil seal correctly is essential for ensuring optimal performance and longevity of your equipment. This guide provides detailed instructions on preparing for installation, executing various installation techniques, and avoiding common errors. Our step-by-step approach will help you achieve a reliable seal every time, preventing leaks and mechanical failures.
