They are typically made from elastomers such as rubber or silicone and consist of an outer metal case with a sealing lip on the inner side.
Duplex Oil Seals


In conclusion, square rubber gaskets are versatile sealing solutions that play a vital role in various mechanical applications. Their flexibility, durability, and reliability make them an essential component for ensuring leak-free and efficient operations. By choosing high-quality square rubber gaskets and following proper maintenance practices, users can enjoy long-lasting and effective sealing solutions for their applications.
These types are made with a metal outer case and a PTFE lip. They are suitable for a wide range of temperatures from -90 °C to +260 °C.These lip seals can also be used for higher pressures of up to 10 bar (special types up to 25 bar) and rotational speeds of up to 40-45 m/s. Certain grades of PTFE are suitable for use in pharmaceutical and food applications. One important point is that PTFE lip seals do require a shaft with a harder, smoother finish.
An oil seal consists of:
Oil seals go by many names, such as shaft seals, dirt seals, grease seals, lip seals, and many other variations of these. They are essentially simple devices used in rotary shaft equipment to prevent lubricant from escaping and for excluding contaminants such as dust, dirt and water. An oil seal’s most important function, however, is that it protects every type of ball, sleeve and roller bearing in the rotating shafts. The seals also prevent the integration of two different fluids that shouldn’t mix, such as oil and water.
A number of variables must be considered when selecting oil seals. There are nine factors that designers and maintenance engineers must evaluate when oil seals are specified:


Lip Seals
Imperfections on the shaft






Our suppliers try to provide the best quality oil seals and products are in some cases optimised to improve performance and fitment. Corteco is one of these brands, whose case studies we have listed for you.
