What is Viton O-rings?

What is Viton O-rings?

Viton® O-Rings Viton is a brand of synthetic rubber and fluoropolymer elastomer commonly used in O-rings and other molded extruded goods. Viton is a registered trademark of DuPont and is sometimes generically referred to as FKM.

Do they make metric O-rings?

Thousands of common metric o-rings and non-standard o-rings in metric sizes are available in stock. Custom o-rings are available upon request and can typically be produced within a few weeks with no tooling fees.

What is an FKM o-ring?

This rubber is used in applications that need O-rings that are resistant to high temperatures and chemical attacks. The FPM/FKM Viton® sealing rings are often used aircraft, automobile and other mechanical devices requiring maximum resistance to elevated temperatures and to many fluids, or other media.

Is FKM same as Viton?

These rubber compounds give exceptional heat resistance with compatibility across many fluids or chemical exposures. The most commonly known name for these compounds is “Viton,”™ which has become the generic name for all FKM polymers and rubber compounds.

What’s the difference between nitrile and Viton O-rings?

What is the Difference Between Nitrile and Viton? Nitrile rubber and Viton are two elastomer polymer types that are different in their appearance and density. Nitrile compounds are organic compounds having the general chemical formula R-CN while Viton is a brand name of synthetic rubber and fluoropolymer elastomers.

What size is an O ring in MM?

O-Ring size is defined by inside diameter and cross-section (width) and is listed in both fractional and decimal dimensions with tolerances. The standards range in I.D.’s from . 74 mm to 658.88 mm and cross sections (widths) from 1.02 mm to 6.99 mm.

What is the difference between EPDM and FKM O-rings?

EPDM (EP, EPR, Ethylene-Propylene Rubber) Both materials are well suited for use in the -30 to 150°C range. FKM has an advantage in lower temperatures and EPDM has an advantage in higher temperatures.

What is Viton FKM?

FKM (FPM, Viton®, Fluorel®) resist mineral oils and greases, aliphatic, aromatic and also special chlorinated hydrocarbons, petrol, diesel fuels, silicone oils and greases. It is suitable for high vacuum applications.

Is Viton an FKM or FFKM?

Both materials are well suited for use in the -15 to 205°C range. FKM has an advantage in lower temperatures and FFKM has an advantage in higher temperatures. Marco offers specific compound formulations extending these ranges even futher as can be seen in the following compound comparison chart.

What color are VITON O-rings?

O-Ring Colors

Is VITON better than silicone?

Both materials are well suited for use in the -30 to 205°C range. Silicone has an advantage in lower temperatures and Silicone has an advantage in higher temperatures. Marco offers specific compound formulations extending these ranges even futher as can be seen in the following compound comparison chart.

What color are Viton O-rings?

What is another name for Viton?

As mentioned, Viton is DuPont’s (now Chemours) brand name for fluorocarbon rubber. This is a synthetic rubber and fluoropolymer elastomer and is commonly used for O-rings and other molded or extruded parts.

Are there different types of Viton?

There are four major families of Viton™ fluoroelastomers: A, B, F, and ETP, each with its own unique performance characteristics. A major differentiator between the Viton™ product families is fluid resistance, which is based on the polymer’s fluorine level.

What is the difference between metric and standard O-rings?

Standard and Metric O-Rings Dimensions There are two main o-ring sizing types: standard and metric. Standard was developed for use in the United States, while the international community uses metric sizes. The metric sizes are further broken down by region, notably Europe and Japan.

How are metric O-rings measured?

O-rings are measured in millimeters. To measure the outside diameter, use a ruler or calipers to measure from one outer corner of the O-ring to the other outer corner. Measure cross section. Place the O-ring into a vernier caliper. Lightly clamp the jaws of the caliper onto the O-ring, but do not compress it.

What are the features of Viton® O-rings?

Features Of Viton® O-Rings: 1 Situational service life above 200°C 2 Excellent resistance to acids, fuels, mineral and vegetable oils and greases, aliphatic, aromatic and chlorinated… 3 Excellent resistance to aging and ozone. 4 Low gas permeability, low compression set. More

Can Viton O rings be used with benzene?

These Viton® fluoroelastomer O-rings resist a wide range of chemicals, including benzene, butyl alcohol, and ethylene glycol. Use these O-rings with metric sanitary fittings, which are sometimes called aseptic fittings.

What is the best sealant for O rings?

Viton® O-Ring and seal performance cost benefit makes it the second most popular sealing material. Fluoroelastomer (Viton®, FKM) offers a wide range of resistance to chemicals, oil and heat, with situational service life above 200°C.
