Viton Rubber O Rings

The Customized Viton Rubber O-Ring from Best Seal is a premium high-performance sealing component engineered for harsh industrial, automotive, chemical, and high-temperature environments. Manufactured from advanced Fluorocarbon Rubber (FKM/Viton), it offers outstanding resistance to high temperatures, strong acids, fuels, solvents, and aggressive chemicals-making it one of the most reliable sealing materials for demanding applications.

Our Viton O-Rings are produced using precision molding technology and strict quality control under ISO 9001, CE, UL, FDA, NSF, WRAS, RoHS, REACH, and SGS certifications. With a hardness range of 20–90 Shore A and an operating temperature of -20°C to +200°C (and up to +230°C in special formulations), they maintain excellent sealing stability under pressure, vibration, and extreme thermal cycling.

We provide both standard AS568 sizes and fully customized dimensions, ensuring a perfect fit for a wide range of equipment and sealing systems. Color, hardness, and formulation can all be tailored to meet specific performance requirements. With a daily production capacity of 5 million pieces, Best Seal ensures fast delivery and consistent quality for both small-batch and large-volume orders.

Viton Rubber O-Ring is made from fluorocarbon elastomer (FKM), a copolymer of vinylidene fluoride (VDF) with hexafluoropropylene (HFP), tetrafluoroethylene (TFE), or perfluoromethyl vinyl ether (PMVE). It is a high-performance material developed to withstand extreme environments and aggressive chemicals.

FKM (commonly known by the DuPont trade name Viton®) is produced through advanced polymerization processes that provide exceptional resistance to high temperatures, oils, fuels, solvents, and most chemicals.

Viton rubber exhibits outstanding heat resistance, oil resistance, and chemical stability, maintaining elasticity and sealing strength even after long-term exposure to harsh media.

Due to its superior sealing reliability and long service life, Viton O-Rings are widely used in automotive, aerospace, chemical, petroleum, and high-vacuum systems, where performance and durability are critical.

Common trade names include Viton® (DuPont), Dai-El® (Daikin), Fluorel® (3M), Tecnoflon® (Solvay), and Dyneon® (3M).

Quality Indicators:

Viton Rubber O-Rings are engineered for environments requiring high temperature and chemical resistance. They maintain sealing integrity even in the presence of fuel, oil, solvent, acid, or ozone.

Typical application industries include:

Automotive – engine seals, fuel injection systems, turbochargers
