The oil seal is a critical component that ensures the sealing of lubricant products and is capable of tolerating axial rotational or sliding movements. Composed of a metal structure that provides strength and stability, along with a coating compound and a sealing lip (possibly supported by a spring), the oil seal is used in applications where a perfect seal for oils, greases, and similar products around rotating shafts is required. But what materials are used for oil seals, particularly for the sealing lip? And why is the Viton oil seal considered one of the best standards in this field?
Materials for Sealing Lips
Among the main materials used in the production of sealing lips, nitrile is one of the most common. It is suitable for most applications and can typically withstand a broad temperature range, from -35°C to +125°C. If a more premium and versatile material is preferred (or required), silicone may be used. Silicone is an elastomer that is particularly resistant to lower temperatures (down to -65°C) or higher temperatures (up to +170°C).
Viton Oil Seal
For those seeking the highest quality, the Viton oil seal is the go-to choice. This premium fluorinated elastomer can withstand temperatures up to +240°C and offers excellent resistance to oils, acids, and other substances that might degrade nitrile or silicone. It is, therefore, a top-quality option with outstanding, long-lasting performance.
As expected, given its superior quality and features compared to competitors, the Viton oil seal is priced higher. However, this additional cost is well justified by its enhanced quality, sealing capacity, and reference performance. It is the ideal choice for situations where a top-tier material is required that can resist substances likely to rapidly degrade nitrile and silicone.
