Technical data - O-ring 69.22x5.33 mm FPM FKM 80 ShA

The 80 designation for this product indicates a specified elastomer hardness of 80 Shore A. However, the exact FKM compound formulation, colour, approvals, compound manufacturer and detailed operating temperature range cannot be determined from the product designation alone and should not be assumed without additional material documentation.

What does O-ring 69.22x5.33 80FPM FKM Viton mean?

The designation identifies the key product parameters:

• O-ring - elastomeric sealing ring with a circular cross-section
• 69.22 mm - inside diameter
• 5.33 mm - cross-section diameter
• 80 - specified hardness of 80 Shore A
• 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

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

What does 80 ShA hardness mean?

80 ShA indicates the elastomer hardness measured on the Shore A scale.

Compared with a typical 70 ShA O-ring, an 80 ShA material is harder and less easily deformed under the same applied force.

O-ring hardness influences factors including:

• deformation inside the groove
• assembly force
• behaviour under pressure
• resistance to extrusion into clearances
• ability to conform to mating surfaces
• overall sealing behaviour

This does not mean that an 80 ShA O-ring is automatically better than a 70 ShA version. The correct hardness should be selected according to groove design and actual operating conditions.

Construction of the FKM 69.22x5.33 mm O-ring

The 69.22x5.33 mm O-ring is a closed elastomeric sealing ring with a round cross-section.

Its basic dimensions are:

• inside diameter: 69.22 mm
• cross-section diameter: 5.33 mm

A standard O-ring does not have a sealing lip, metal case or garter spring.

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

Depending on groove design, pressure, speed and other 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 used extensively 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.

Actual chemical resistance depends on the specific compound and operating conditions.

Before use, verify:

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

Operating temperature of the FKM 80 ShA O-ring

A single operating temperature range should not be assigned to this product solely on the basis of the FKM designation and 80 ShA hardness.

FKM is a family containing different fluoroelastomer compounds. A hardness of 80 ShA also does not define the exact material formulation.

Individual FKM compounds can differ in high-temperature capability, low-temperature behaviour, chemical resistance and compression set.

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

FKM 80 ShA vs FKM 70 ShA O-ring

FKM O-rings with identical dimensions can be manufactured in different hardness grades.

70 ShA and 80 ShA versions should not automatically be considered interchangeable.

An FKM 80 ShA O-ring is harder than a 70 ShA equivalent. As a result, it may behave differently during installation, compression and operation under pressure.

Before changing hardness, verify:

• groove design
• required compression
• operating pressure
• extrusion gap
• static or dynamic operation
• requirements of the specific application

Identical dimensions and the same elastomer family do not guarantee full interchangeability when hardness differs.

FKM 69.22x5.33 O-ring vs NBR 69.22x5.33 O-ring

An FKM 69.22x5.33 mm O-ring and an NBR 69.22x5.33 mm O-ring may have identical dimensions but are made from different elastomer materials.

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 oils and lubricants but has different chemical and thermal characteristics.

Changing the elastomer material requires assessment of the actual operating conditions.

How to select an O-ring 69.22x5.33 mm FKM 80 ShA

Before ordering, verify:

• inside diameter: 69.22 mm
• cross-section: 5.33 mm
• FPM / FKM material
• hardness: 80 ShA
• operating medium
• operating temperature
• system pressure
• groove design
• required O-ring compression
• extrusion clearance
• static or dynamic operation
• required material approvals

For this product, three parameters are particularly important for identification:

69.22x5.33 mm + FKM/FPM + 80 ShA.

An O-ring with identical dimensions but a different elastomer material or hardness should not automatically be considered a direct replacement.

They do not confirm that this specific 69.22x5.33 mm FKM 80 ShA O-ring is intended for a particular vehicle, machine, engine, gearbox or OEM application.

Installation of the FKM 69.22x5.33 mm O-ring

Before installation, carefully clean the groove and mating surfaces.

During installation, avoid:

• cutting the O-ring
• 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 both the FKM compound and the operating medium.
