About Viton O'Rings

Rubber O Rings are precisely designed sealing components that are notable for their torus shape. These are installed in groove section of single or multiple parts by applying compression force for attaining hermetic fastening result. In brief, these are the elastomer loops that are noteworthy for their cross and circular sectional design.

The offered sealing rings are suitable both for passive and active works utilization purpose. Being cost effective, these are considered as the most ergonomic sealing components available in the market. Simple manufacturing technique, trouble free usage and easy fitting method are some key attributes of these sealing parts.

Based on their hardness level and materials of construction, these o rings are used as essential sealing materials for equipments like filters, generators, lubricating systems, compressors, LPG regulators, gas-springs, valves and pumps, pneumatic and hydraulic cylinders, automobiles and actuators to name a few.

We have grown expertise in the manufacturing arena of Rubber O Rings that are made of standard grade rubbers like EPDM, neoprene, silicon, natural, viton, nitrile and others.

Customers can obtain these o rings in different metric size options, in non standard and standard dimension range from the huge collection of MREW. Clients can also attain these o rings in required size or fluid resistance configurations from this organization.

Apart from providing standard o rings, MREW is also instrumental in offering these with latest sealing design options like Quad Rings® that are used for low pressure sealing purpose

Unmatched Chemical Resistance

Viton O-Rings excel in environments exposed to aliphatic and aromatic hydrocarbons, acids, solvents, and oils. Their outstanding chemical resistance ensures long-lasting performance even in the harshest industrial settings, including chemical processing plants and refineries.

Exceptional Temperature Tolerance

Constructed from premium FKM, these O-Rings function reliably between -20C and +200C, withstanding short bursts up to +250C. Their remarkable thermal stability makes them suitable for both high-heat and sub-zero operational conditions.

Wide Range of Applications

With standard and custom widths from 1 mm to 25 mm, and inner diameters from 2 mm to 500 mm, Viton O-Rings meet diverse sealing requirements. They are commonly used in hydraulic and pneumatic systems, automotive engines, pharmaceutical equipment, and aerospace assemblies for robust, leak-proof sealing.

FAQs of Viton ORings:

Q: How should Viton O-Rings be stored to maximize their shelf life?

A: For optimal longevity, Viton O-Rings should be kept in a cool, dry place, away from direct sunlight or sources of ozone. Under such proper storage conditions, they maintain their sealing properties for up to 5 years.

Q: What makes Viton O-Rings particularly suitable for use in chemical processing industries?

A: Viton O-Rings offer superior resistance to a wide array of chemicalsaliphatic and aromatic hydrocarbons, strong acids, oils, and solventsmaking them ideal for sealing in rigorous chemical processing applications.

Q: When is it necessary to use Viton O-Rings instead of natural rubber or standard elastomers?

A: Viton O-Rings are recommended when dealing with aggressive chemicals, high temperatures (up to +200C), or demanding environments where conventional rubber would degrade. Their synthetic FKM base ensures durability and excellent sealing even under harsh conditions.

Q: Where are Viton O-Rings most commonly installed?

A: These O-Rings are widely used in hydraulic and pneumatic systems, automotive components, pharmaceutical equipment, aerospace machinery, and other critical environments that demand chemical resistance and reliable sealing.

Q: What process ensures the quality and precision of Viton O-Rings?

A: Each Viton O-Ring is factory-molded with precise tolerances (0.05 mm), subject to rigorous quality control, and packed in polybags or boxes to prevent contamination or deformation, thereby guaranteeing seal integrity during use.

Q: How does using Viton O-Rings benefit industrial operations?

A: Choosing Viton O-Rings reduces maintenance needs, minimizes risk of leaks, improves system longevity, and ensures safe, reliable performance even under extreme chemical exposure and temperature swings.
