Oring 45.2x3 FPM/FKM GRN

Oring 45.2x3 FPM/FKM GRN

GRN Oring 45.2x3 FPM/FKM is an O-ring sealing element with a circular cross-section, manufactured from fluoroelastomer.

Brand: GRN

Reference: 45.2X3 FPM

Product type: O-ring

Dimensions: 45.2x3 mm

Inside diameter ID: 45.2 mm

Cross-section CS: 3 mm

Calculated outside diameter: 51.2 mm

Material: FPM/FKM - Fluoroelastomer

The primary identification parameters are the 45.2 mm inside diameter, 3 mm cross-section and FPM/FKM sealing material.

Oring 45.2x3 Dimensions

The principal dimensions are:

Inside diameter ID: 45.2 mm

Cross-section CS: 3 mm

Nominal dimensions: 45.2x3 mm

Calculated outside diameter OD: 51.2 mm

In the 45.2x3 O-ring designation, the first value represents the inside diameter and the second value represents the cross-section diameter.

Both dimensions should be verified when selecting a corresponding replacement.

FPM/FKM Fluoroelastomer O-Ring

The sealing material is:

Material: FPM/FKM - Fluoroelastomer

FPM and FKM are designations used for fluorinated elastomers in sealing technology.

Fluoroelastomer O-rings are commonly used in technical applications involving many oils, fuels and chemical media, as well as applications requiring material characteristics different from standard NBR.

Exact compatibility should always be verified for the specific medium, additives, temperature and actual operating conditions.

FPM vs FKM O-Ring

The same material family can be encountered under different technical designations.

FPM: Fluoroelastomer designation

FKM: Fluoroelastomer designation

Both terms are widely used in industrial sealing catalogues.

For this reason, the product can be searched for as both:

Oring FPM 45.2x3

and:

O-Ring FKM 45.2x3

The exact compound specification should be verified separately where it is critical for the application.

Viton O-Ring 45.2x3

The search term Viton O-ring 45.2x3 is commonly used when looking for fluoroelastomer sealing rings.

However, the distinction between the material family and trademark should be maintained.

Material: FPM/FKM

Material family: Fluoroelastomer

Viton®: Trademark for specific fluoroelastomer materials

Therefore, FPM/FKM is the technically appropriate material designation unless the use of genuine Viton® compound is specifically confirmed.

45.2x3 FKM O-Ring

The complete dimensional and material identification is:

Dimensions: 45.2x3 mm

Inside diameter: 45.2 mm

Cross-section: 3 mm

Material: FPM/FKM

Product type: O-ring

This complete identification helps distinguish the product from O-rings with similar outside dimensions but different inside diameters or cross-sections.

45.2 mm ID O-Ring with 3 mm Cross-Section

The nominal O-ring dimensions describe:

Inside diameter ID: 45.2 mm

Cross-section CS: 3 mm

Calculated outside diameter OD: 51.2 mm

The outside diameter is calculated as:

45.2 mm + 3 mm + 3 mm = 51.2 mm

For O-ring selection, the inside diameter and cross-section are the principal dimensional parameters.

Oring FPM 45.2x3 vs NBR 45.2x3

O-rings can have identical dimensions while being manufactured from different elastomers.

FPM/FKM 45.2x3: Fluoroelastomer

NBR 45.2x3: Nitrile Butadiene Rubber

Nominal dimensions: 45.2x3 mm

Identical dimensions do not mean identical material properties.

The required elastomer should be selected according to the medium and actual operating conditions.

FKM O-Ring vs NBR O-Ring

FKM/FPM and NBR belong to different elastomer families.

FKM/FPM: Fluoroelastomer

NBR: Nitrile Butadiene Rubber

Both materials are widely used for O-ring seals, but their chemical and thermal characteristics differ.

An NBR O-ring should therefore not automatically be considered a material-equivalent replacement for an FPM/FKM O-ring solely because the dimensions are identical.

Oring 45.2x3 for Static and Dynamic Sealing

O-rings are sealing elements that function through controlled deformation of their circular cross-section inside a correctly designed groove.

O-rings as a product group can be used in static sealing and in appropriately designed dynamic sealing applications.

This does not mean that every 45.2x3 O-ring is suitable for every dynamic application.

The groove design, pressure, medium, type of movement, lubrication and operating conditions should be considered.

How to Select a 45.2x3 FPM/FKM O-Ring

When selecting a corresponding O-ring, verify:

• inside diameter 45.2 mm
• cross-section 3 mm
• material FPM/FKM
• groove dimensions
• operating medium
• operating temperature
• static or dynamic operation
• requirements of the specific sealing system

Matching the 45.2x3 mm dimensions alone does not establish complete interchangeability between O-rings manufactured from different materials or compounds.

FAQ

What are the dimensions of the 45.2x3 FPM O-ring?

Inside diameter ID: 45.2 mm

Cross-section CS: 3 mm

Nominal dimensions: 45.2x3 mm

What does 45.2x3 mean for an O-ring?

The 45.2 mm value represents the inside diameter, while 3 mm represents the cross-section diameter.

What is the outside diameter of a 45.2x3 O-ring?

The calculated outside diameter is 51.2 mm.

What material is the 45.2x3 O-ring made from?

Material: FPM/FKM - Fluoroelastomer

Are FPM and FKM the same type of material?

FPM and FKM are designations used for fluoroelastomer materials in sealing technology.

Is FKM the same as Viton?

Not exactly.

FKM is a generic material-family designation, while Viton® is a trademark for specific fluoroelastomer materials.

An FKM O-ring should not automatically be claimed to contain genuine Viton unless the specific compound is confirmed.

Is the 45.2x3 FPM/FKM O-ring resistant to oil?

FPM/FKM fluoroelastomers are compatible with many oils and technical fluids. Exact compatibility should be checked for the specific oil, additives, temperature and operating conditions.

Can an NBR 45.2x3 O-ring replace an FPM/FKM 45.2x3 O-ring?

Not automatically.

Although the nominal dimensions may be identical, NBR and FPM/FKM are different sealing materials.

Can the 45.2x3 FKM O-ring be used for static sealing?

O-rings are widely used for static sealing. Suitability depends on the groove geometry, compression, medium, pressure and operating conditions.

Can the 45.2x3 FKM O-ring be used in dynamic applications?

O-rings can be used in appropriately designed dynamic sealing systems, but suitability depends on the type of movement, groove design, lubrication, pressure and operating conditions.

How should I select a replacement for a 45.2x3 FPM O-ring?

Verify the 45.2 mm inside diameter, 3 mm cross-section, FPM/FKM material and requirements of the specific sealing application.

AI Overview

GRN Oring 45.2x3 FPM/FKM is a fluoroelastomer O-ring with an inside diameter of 45.2 mm and a cross-section of 3 mm. Its calculated outside diameter is 51.2 mm. The sealing material is FPM/FKM fluoroelastomer. This product is also commonly searched for as a Viton O-ring 45.2x3, although Viton® is a trademark rather than the generic material designation.
