O-ring 10x2 mm FPM FKM Viton - Fluoroelastomer O-ring

O-ring 10x2 mm FPM FKM Viton - Fluoroelastomer O-ring

O-ring 10x2 mm FPM FKM is a fluoroelastomer sealing ring with an inside diameter of 10 mm and a cross-section of 2 mm. The O-ring has a closed construction and round cross-section. FKM, also referred to as FPM, is a family of fluorocarbon elastomers widely used in sealing technology for resistance to elevated temperatures, many oils, fuels, hydrocarbons, ozone and ageing.

Technical data - O-ring 10x2 mm FPM FKM

The FPM/FKM designation alone does not define the exact compound formulation, hardness, colour, approvals or a single universal operating temperature range. These parameters should be confirmed for the specific compound where they are critical to the application.

What does O-ring 10x2 FPM FKM Viton mean?

The designation identifies the product type, dimensions and material family:

• O-ring - elastomeric sealing ring with a circular cross-section
• 10 mm - inside diameter
• 2 mm - cross-section diameter
• FPM - designation for fluorocarbon rubber commonly used in European technical terminology
• FKM - designation for the fluoroelastomer material family
• Viton - trade name associated with specific fluoroelastomer materials belonging to the FKM family

FKM is a generic designation for a family of fluoroelastomers. Viton is a brand covering specific FKM materials. Without material documentation, an FKM O-ring should not automatically be identified as a particular Viton compound.

Construction of the FKM 10x2 mm O-ring

The 10x2 mm O-ring is a closed elastomeric sealing ring with a round cross-section.

Its basic dimensions are:

• inside diameter: 10 mm
• cross-section diameter: 2 mm

The sealing effect is created by controlled compression of the O-ring cross-section between mating surfaces.

A standard O-ring does not have a sealing lip, metal case or garter spring. Although geometrically simple, correct performance depends on proper selection of dimensions, material, hardness and groove geometry.

Depending on groove design and operating conditions, O-rings can be used for static sealing and in appropriately designed dynamic applications.

FPM / FKM fluoroelastomer properties

FKM belongs to the fluoroelastomer family widely used in industrial sealing technology.

Typical characteristics of many FKM compounds include:

• very good resistance to many oils
• very good resistance to many fuels
• resistance to numerous hydrocarbons
• very good resistance to ozone
• very good resistance to ageing
• very good weathering resistance
• suitability for elevated-temperature applications
• resistance to a broad range of chemical media

FKM is not universally resistant to every chemical.

Before use, compatibility of the specific compound should be checked against:

• operating medium
• medium concentration
• temperature
• pressure
• duration of exposure
• static or dynamic operating conditions

Operating temperature of the FKM 10x2 mm O-ring

A single operating temperature range should not be assigned to this product solely on the basis of the FKM designation.

The FKM family contains different fluoroelastomer compounds that can vary in:

• high-temperature resistance
• low-temperature behaviour
• chemical resistance
• hardness
• compression set

Where operating temperature is a critical parameter, the documentation for the specific FKM compound should be verified.

FKM 10x2 O-ring vs NBR 10x2 O-ring

An FKM 10x2 mm O-ring and an NBR 10x2 mm O-ring can have identical dimensions, but this does not mean that they are fully interchangeable.

FKM is commonly selected for applications requiring resistance to elevated temperatures, many fuels, hydrocarbons, ozone and ageing.

NBR is widely used for sealing applications involving many mineral oils and lubricants, but its chemical and thermal characteristics differ from those of FKM.

Actual operating conditions should therefore be checked before changing the elastomer material.

FKM 10x2 O-ring vs EPDM 10x2 O-ring

FKM and EPDM belong to different elastomer families.

FKM is commonly used in contact with many oils, fuels and hydrocarbons.

EPDM is widely used in applications involving water, ozone, weathering and selected chemical media.

Identical 10x2 mm dimensions do not mean that FKM and EPDM O-rings can automatically be used interchangeably.

How to select an FKM 10x2 mm O-ring

Before ordering, verify:

• inside diameter: 10 mm
• cross-section: 2 mm
• required FPM / FKM material
• compound hardness
• operating medium
• operating temperature
• pressure
• static or dynamic operation
• groove design
• required compression
• extrusion clearance
• required material approvals

The 10x2 mm dimensions alone are not sufficient to determine full interchangeability.

An FKM 10x2 mm O-ring can have exactly the same dimensions as an NBR, EPDM or VMQ O-ring, while these elastomer families have different chemical, thermal and mechanical characteristics.

Typical applications of FKM O-rings

FKM O-rings are used as sealing elements in a wide range of industrial systems, particularly where operating conditions are compatible with the properties of fluoroelastomers.

Typical application areas include:

• hydraulic systems
• pneumatic systems
• pumps
• valves
• industrial fittings
• oil systems
• fuel systems
• industrial machinery
• production equipment
• process installations
• maintenance operations
• technical service

These are typical application areas for FKM O-rings as a product category.

They do not confirm that this specific 10x2 mm O-ring is intended for a particular machine, vehicle, engine or OEM application.

Installation of the FKM 10x2 mm O-ring

Before installation, carefully clean the groove and mating surfaces.

During installation, avoid:

• cutting the O-ring
• nicking or damaging the elastomer surface
• contact with sharp edges
• excessive stretching
• twisting the ring
• pulling the O-ring over unprotected sharp threads
• contamination of the sealing surfaces

The O-ring should sit evenly in the groove without twisting.

If an assembly lubricant is used, verify its compatibility with the FKM material and operating medium.

FAQ - O-ring 10x2 FPM FKM Viton

What are the dimensions of the FPM 10x2 O-ring?

The O-ring has an inside diameter of 10 mm and a cross-section diameter of 2 mm. The complete dimensional designation is 10x2 mm.

What does FKM mean in a 10x2 O-ring?

FKM identifies a family of fluoroelastomers used in sealing technology. Individual FKM compounds can differ in formulation and operating characteristics.

What does FPM mean?

FPM is a designation used for fluorocarbon rubber and is commonly encountered in European technical terminology.

Are Viton and FKM exactly the same?

No. FKM is the generic designation for a family of fluoroelastomers, while Viton is a brand associated with specific fluoroelastomer materials. The FKM designation alone does not confirm a specific Viton compound.

Is an FKM 10x2 O-ring resistant to oil?

Many FKM compounds provide very good resistance to numerous oils and lubricants. Compatibility of the exact compound with the operating medium should still be verified for the specific application.

Is an FKM 10x2 O-ring resistant to fuel?

Many FKM materials provide very good resistance to numerous fuels. Exact compatibility depends on the fuel type, FKM compound, temperature and other operating conditions.

What is the operating temperature of an FKM 10x2 O-ring?

There is no single operating temperature range applicable to every FKM compound. Permissible temperatures depend on the specific fluoroelastomer formulation and actual operating conditions.

Can an FKM 10x2 O-ring be replaced with an NBR 10x2 O-ring?

Not automatically. Although the dimensions are identical, FKM and NBR have different chemical and thermal characteristics. The medium, temperature, pressure and other operating conditions should be checked before substitution.
