O-ring FPM 122x3,5 FKM Viton Fluor Technical Sealing

O-ring FPM 122x3.5 FKM Viton Fluor Technical Sealing Ring

Oring FPM 122x3.5 made from FKM fluorocarbon rubber also known as Viton is a high performance technical sealing ring designed for demanding industrial environments requiring resistance to heat, oils, fuels and aggressive chemicals.

This FKM sealing Oring belongs to the group of fluorocarbon technical seals used in industrial systems, where conventional elastomers such as NBR may not provide sufficient chemical stability or temperature resistance.

The dimension 122x3.5 FPM Oring is commonly used in pumps, hydraulic equipment and chemical processing installations where long term sealing reliability and resistance to aggressive media are required.

Material and sealing design

The Oring FPM is manufactured from fluorocarbon elastomer widely known as FKM or Viton. This material provides excellent resistance to:

high operating temperatures
mineral and synthetic oils
fuel and hydrocarbons
many aggressive chemical substances
oxidation and thermal aging

The circular cross section ensures uniform compression and reliable sealing between mechanical components.

Because of these characteristics, FKM Viton Orings are widely used as industrial sealing elements in high performance applications.

Industrial applications

FPM fluorocarbon Orings such as the 122x3.5 FKM sealing ring are used in installations where chemical resistance and thermal stability are critical.

Typical applications include:

industrial pumps
hydraulic systems
chemical processing installations
petrochemical equipment
fuel systems
industrial machinery
automotive sealing systems

In many systems FKM Orings replace standard NBR seals where higher temperature resistance and chemical stability are required.

Operational advantages

FPM Viton Orings provide several important advantages in demanding industrial sealing applications.

high resistance to heat
excellent chemical resistance
long service life
stable sealing performance
high resistance to oils and fuels

These characteristics make fluorocarbon Orings one of the most reliable sealing solutions used in modern industry.

Role in the FKM Oring category

The Oring FPM 122x3.5 belongs to the wider group of fluorocarbon sealing rings used in industrial and mechanical equipment. Within the category of FKM FPM Viton Orings, this dimension is frequently applied in systems requiring precise sealing combined with chemical durability.

Sizes such as 122x3.5 FKM Oring are commonly selected for medium diameter sealing applications where stable compression and long service intervals are required.

FAQ

What is FPM or FKM material in Orings

FPM also known as FKM is a fluorocarbon elastomer widely used for high temperature and chemical resistant sealing applications.

What temperature can FKM Orings withstand

Standard FKM Orings typically operate in temperatures up to about 200 degrees C depending on the application and operating conditions.

Are FKM Orings resistant to fuel and oil

Yes. FKM Viton material provides excellent resistance to fuels, oils and hydrocarbons.

When should FKM Orings be used instead of NBR

FKM Orings are recommended when applications involve high temperatures, aggressive chemicals or fuels where NBR seals may degrade faster.
