O-Ring 93x3.5 mm Dimensions

The designation 93x3.5 mm means:

• 93 mm - inside diameter ID
• 3.5 mm - cross-section CS

The nominal outside diameter is calculated using:

OD = ID + 2 x CS

For this O-ring:

OD = 93 mm + 2 x 3.5 mm = 100 mm

What Is FPM?

FPM is a designation used for fluorocarbon elastomers belonging to the fluoroelastomer family.

FPM/FKM materials are widely used in sealing technology, particularly under demanding operating conditions.

Depending on the exact compound, FPM/FKM O-rings can provide very good performance with many:

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

FKM is also frequently selected for sealing systems operating at elevated temperatures.

Exact performance depends on the specific 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:

FPM O-Ring 93x3.5 mm

or:

FKM O-Ring 93x3.5 mm

However, individual FKM compounds can differ in chemical resistance, temperature capability and mechanical properties.

FKM vs Viton® - Are They the Same?

Not exactly.

FKM is a generic designation for a class of fluoroelastomers.

Viton® is a trademark for specific fluoroelastomer materials.

The phrase:

Viton O-Ring 93x3.5 mm

is commonly used by customers searching for fluoroelastomer O-rings. However, not every FKM O-ring should automatically be described as genuine Viton® unless the exact branded compound is confirmed by product documentation.

For an unspecified fluoroelastomer compound, FPM/FKM is the technically appropriate material designation.

FKM O-Ring 93x3.5 mm for Oil

FKM is widely used for seals exposed to many oils and lubricants.

Depending on the exact compound and operating conditions, an FKM 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, temperature and FKM compound.

FKM O-Ring 93x3.5 mm for Fuel

FKM is frequently selected for sealing applications involving fuels and hydrocarbons.

Typical applications can include:

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

Exact compatibility depends on the FKM compound and fuel formulation, including additives and bio-components.

FKM O-Ring for High Temperature Applications

FKM fluoroelastomers are widely used where sealing systems are exposed to more demanding temperature conditions than many conventional elastomers.

There is no single universal operating temperature range for every FKM compound.

Actual temperature capability depends on:

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

Technical data for the specific compound should be checked for applications operating close to material limits.

Chemical Resistance of FKM O-Rings

FKM provides a broad chemical resistance profile, but it is not universally resistant to every substance.

Correct material selection should consider:

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

For demanding chemical applications, compatibility should be verified for the specific compound and medium.

FKM vs NBR

FKM and NBR belong to different elastomer families.

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

FKM is frequently selected for more demanding operating conditions involving:

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

An NBR O-Ring 93x3.5 mm should therefore not automatically replace an FKM O-Ring 93x3.5 mm.

FKM vs EPDM

FKM and EPDM have significantly different chemical resistance profiles.

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

FKM is more commonly selected for many oil, fuel and hydrocarbon applications.

Identical dimensions do not make these materials 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 appropriate oils, fuels and hydrocarbons is required, particularly under demanding operating conditions.

Material selection should always be based on the actual application.

Typical Applications of FPM O-Ring 93x3.5 mm

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 should always 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 93x3.5 mm 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 dimensions alone do not confirm suitability for a specific dynamic application.

How to Select an FPM O-Ring 93x3.5 mm

Before ordering, check:

1. Inside diameter ID - 93 mm
2. Cross-section CS - 3.5 mm
3. Outside diameter OD - approximately 100 mm
4. Material - FPM/FKM
5. Required compound hardness
6. Operating medium
7. Temperature
8. Pressure
9. Static or dynamic operation
10. Groove geometry
11. Required approvals or certifications

The basic dimensional identification is:

ID 93 mm + CS 3.5 mm + OD approximately 100 mm

Are All 93x3.5 mm O-Rings Interchangeable?

No.

O-rings with identical dimensions may be manufactured from different materials, including:

• FKM/FPM
• NBR
• EPDM
• VMQ
• FVMQ

They may also differ in hardness, compound formulation, tolerances and approvals.

Dimensions alone do not confirm interchangeability.

Does O-Ring Colour Confirm FKM Material?

No.

Colour is not a reliable method for identifying an elastomer.

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

Material identification should be based on the product specification.

Is an FKM O-Ring Food Grade?

Not automatically.

The FKM designation alone does not confirm suitability for food-contact applications.

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