O-Ring 94x3 mm Dimensions

The designation 94x3 mm means:

• 94 mm - inside diameter ID
• 3 mm - cross-section CS

The nominal outside diameter is calculated using:

OD = ID + 2 x CS

For this O-ring:

OD = 94 mm + 2 x 3 mm = 100 mm

How Is the O-Ring 94x3 mm Sold?

The O-Ring 94x3 mm FKM 80 Shore A is sold individually, allowing the required quantity to be selected according to the customer's technical or purchasing requirements.

For transparent B2B price comparison, the price displayed for this product represents the net price for 100 pieces.

This means:

Sales unit: 1 pc

Displayed price basis: 100 pcs, net

The product should therefore not be interpreted as a pre-packed 100-piece set or a package that can only be purchased in quantities of 100.

This pricing format is particularly useful for industrial buyers, maintenance departments, repair services and purchasing departments comparing the cost of O-rings in larger quantities.

What Does 80 Shore A Mean?

The 80 Shore A designation specifies the nominal hardness of the elastomer.

An 80 ShA FKM O-ring is relatively firm and is less easily deformed than a comparable 70 ShA O-ring.

Hardness can influence:

• deformation under load
• extrusion resistance
• sealing contact
• installation behaviour
• friction
• response to pressure

A higher hardness is not automatically better. The correct hardness depends on the groove geometry, clearance, pressure, movement and operating conditions.

What Is FKM?

FKM is a designation for a family of fluoroelastomers widely used in industrial sealing technology.

Depending on the exact compound, FKM O-rings can provide very good resistance to many:

• mineral oils
• engine oils
• transmission oils
• lubricants
• greases
• fuels
• hydrocarbons
• selected chemicals

FKM is also widely used where sealing systems are exposed to elevated temperatures.

Exact chemical and thermal performance depends on the specific FKM compound and operating conditions.

FPM vs FKM - What Is the Difference?

FPM and FKM are designations associated with the same broad family of fluoroelastomers, although they originate from different nomenclature systems.

This product may therefore be searched for as:

FKM O-Ring 94x3 mm 80 Shore A

or:

FPM O-Ring 94x3 mm 80 Shore A

The exact properties of the seal depend on the specific elastomer compound rather than the dimensional designation alone.

FKM, FPM and Viton®

FKM and FPM are technical designations associated with the fluoroelastomer family.

Viton® is a trademark for specific fluoroelastomer materials and should not be treated as a generic material name for every FKM O-ring.

Unless the exact branded compound is documented, FKM/FPM is the technically appropriate designation.

FKM O-Ring 94x3 mm for Oil

FKM is widely used in sealing systems exposed to many oils and lubricants.

Depending on the exact compound and operating conditions, this O-ring may be suitable for compatible:

• mineral oils
• engine oils
• transmission oils
• industrial oils
• lubricating oils
• greases

Compatibility should always be verified for the specific medium and operating temperature.

FKM O-Ring 94x3 mm for Fuel

FKM is commonly selected for many fuel and hydrocarbon sealing applications.

Typical applications can include:

• fuel systems
• pumps
• valves
• engines
• automotive equipment
• industrial machinery

Compatibility depends on the exact FKM formulation and fuel composition, including additives and bio-components.

FKM O-Ring for Elevated Temperatures

FKM fluoroelastomers are widely used in applications requiring greater heat resistance than many conventional elastomers.

However, there is no single universal operating temperature range for every FKM compound.

Temperature capability depends on:

• exact compound
• operating medium
• exposure duration
• pressure
• seal design
• static or dynamic operation

The technical data for the specific compound should be checked when operating close to material limits.

Chemical Resistance of FKM O-Rings

FKM offers broad chemical resistance, but it is not universally resistant to every substance.

Correct selection should consider:

• operating medium
• chemical concentration
• temperature
• pressure
• exposure time
• exact FKM compound
• static or dynamic operation

For demanding chemical applications, compatibility should be confirmed for the exact compound and medium.

FKM 80 ShA vs FKM 70 ShA

A 94x3 mm FKM 80 Shore A O-ring should not automatically be replaced by a 94x3 mm FKM 70 Shore A O-ring.

Although the dimensions and material family may be the same, hardness is different.

An 80 ShA compound is generally firmer and less deformable than a comparable 70 ShA compound.

The correct hardness should be selected according to:

• pressure
• clearance
• groove geometry
• compression
• movement
• operating conditions

FKM vs NBR

NBR and FKM belong to different elastomer families.

NBR is widely used in standard industrial, hydraulic and oil sealing applications.

FKM is frequently selected for more demanding conditions involving:

• elevated temperatures
• fuels
• hydrocarbons
• oils
• selected chemicals

A 94x3 mm NBR O-ring should therefore not automatically replace a 94x3 mm FKM O-ring.

FKM vs EPDM

FKM and EPDM have different chemical resistance profiles.

EPDM is commonly selected for water, hot water and many compatible water-based media.

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

Identical dimensions do not make FKM and EPDM interchangeable.

FKM vs VMQ Silicone

FKM and VMQ silicone belong to different elastomer families.

VMQ provides a different combination of flexibility, temperature performance and chemical resistance.

FKM is frequently selected where compatibility with oils, fuels, hydrocarbons and elevated temperatures is required.

Material selection should always be based on the actual operating environment.

Typical Applications of O-Ring 94x3 FKM 80 ShA

Depending on operating conditions, this O-ring may be used in:

• industrial machinery
• hydraulic systems
• pneumatic systems
• pumps
• valves
• industrial fittings
• gearboxes
• oil systems
• fuel systems
• engines
• mechanical equipment
• automotive applications
• industrial maintenance
• MRO operations

Suitability for a specific application must be confirmed using the complete operating parameters.

Static Sealing Applications

FKM O-rings are widely used for static sealing in:

• housings
• covers
• flanges
• fittings
• connectors
• machine components
• industrial assemblies

Correct groove dimensions, compression and material compatibility are essential for reliable sealing.

Dynamic Sealing Applications

An FKM 80 ShA O-ring may also be used in appropriately designed dynamic sealing applications.

Additional factors include:

• type of movement
• speed
• friction
• lubrication
• surface finish
• temperature
• pressure
• wear

The size and hardness alone do not confirm suitability for a specific dynamic application.

How to Select an O-Ring 94x3 FKM 80 Shore A

Before ordering or installing the O-ring, check:

1. Inside diameter ID - 94 mm
2. Cross-section CS - 3 mm
3. Outside diameter OD - approximately 100 mm
4. Material - FKM/FPM
5. Hardness - 80 Shore A
6. Operating medium
7. Temperature
8. Pressure
9. Static or dynamic operation
10. Groove geometry
11. Required certifications or approvals

The basic technical identification is:

94x3 mm FKM 80 Shore A

with:

ID 94 mm + CS 3 mm + OD approximately 100 mm

Are All 94x3 mm O-Rings Interchangeable?

No.

O-rings with the same 94x3 mm dimensions can be manufactured from different elastomers, including:

• FKM/FPM
• NBR
• EPDM
• VMQ
• FVMQ

They can also have different hardness values and compound formulations.

The same dimensions alone do not confirm interchangeability.

Does O-Ring Colour Identify FKM?

No.

Colour is not a reliable method for identifying an elastomer.

FKM O-rings can be manufactured in different colours, while visually similar seals can be produced from completely different materials.

Material identification should be based on the product specification.

Is This FKM O-Ring Food Grade?

Not automatically.

The FKM material designation alone does not confirm food-contact compliance.

Where food-contact approval is required, documentation for the exact compound and finished product should be verified.
