FKM Colorful O Ring Rubber O-Rings

SWKS Seal, with over 10 years experience, is one of the leading fkm colorful o ring rubber o-rings manufacturers and suppliers in China. And we also offer the customized service catering to your special requirement. Please be free to buy the rubber products with competitive price from us.

Viton/FKM o-rings offer excellent chemical and temperature resistance and are available in a wide variety of FKM types and formulations. Standard AS568 imperial, metric and non-standard Viton o-ring sizes are kept in stock, and custom Viton o-rings are typically available with no tooling fees and rush deliviers.

Specialty FPM and FKM compounds are available for improved low temperature and chemical resistance. Viton specialty formulations are also available for durometer hardness, colors, food and medical grade, high pressure, and explosive decompression resistance. Viton fluorocarbon compounds are widely used in chemical, aerospace and industrial applications, but are not recommended for use with steam, amines, or polar solvents.

Description

FEP is a thermoplastic material with properties similar to PTFE. O-rings which are seamlessly coated with FEP have an elastic core made from FPM or VMQ and are used if very high thermal or chemical loads are present. The high chemical resistance of the coating protects the core against damage by the potentially aggressive medium.

FEP coated O-rings are used – similar to PTFE-rings – where the chemical resistance of the normal elastomer O-ring is no longer sufficient, but where a certain elasticity is needed. The elasticity is ensured by the inner ring and the chemical resistance is achieved by the seamless FEP coating.

Applications

FEP coated O-rings are perfectly suited for the chemical and petrochemical sector, medical technology, food sector, water and waste water technology and similar industrial applications. A typical application for FEP coated O-rings is the sealing of valve stems and as a secondary sealing element for slow switching and rotary movements.

Properties

·         Very good chemical resistance against most liquids and chemicals

·         Temperature range from approx. –60 °C to 200 °C [depending on inner ring material]

·         No contamination of food, pharmaceutical or medical products

·         Physiologically harmless, can be sterilised

·         Sufficient elastic behaviour

·         FEP O-rings can be replaced with standard O-ring seals without limitation

·         No changes to the groove dimensions are necessary

·         The O-rings are less flexible than elastomer O-rings due to the FEP coating. They can only be stretched minimally and have a lower elasticity or a higher permanent deformation
