Material selection is important to the life of a radial shaft seal. The elastomer’s resistance to temperature, abrasion, chemicals, weather, sunlight, and ozone can affect a profile’s longevity and performance. The two most prevalent materials are Nitrile and Viton. See our Oil Seal Materials page for details on compounds and chemical compatibility.
1. The oil seal consists of a metal ring as the inner skeleton which provides the structural stability to the oil seal.


Some of the uses of o-rings are pipes, plates, flanges, and cylinders. They can also be found in cameras, and scuba gear.
Oil seals come in a range of sizes ranging from 0 cm to 33 cm, and choosing the right size is critical to performance. The size of an oil seal is determined by the following dimensions:
• Total eccentricity
• Rotational speed
• Substance to be sealed
• Lubrication conditions, etc.
