Oil seals are important components used to ensure oil tightness in blowers and compressors. Usually made of rubber, silicone or metal alloys, these seals protect the performance of blowers and compressors and extend their life. Proper selection of oil seals is critical to preventing leaks and increasing energy efficiency. Quality oil seals are resistant to harsh conditions such as abrasion and high temperatures. Proper oil seal selection saves money in the long term by reducing maintenance costs.
