O-Ring 64x1.5 NBR 70 ShA GRN

O-Ring 64x1.5 NBR 70 ShA GRN

GRN O-Ring 64x1.5 NBR 70 ShA is a circular cross-section sealing ring manufactured from nitrile rubber.

Brand: GRN

Reference: 64X1.5

Product type: O-Ring

Dimensions: 64x1.5 mm

Inside diameter ID: 64 mm

Cross-section CS: 1.5 mm

Outside diameter OD: 67 mm

Material: NBR - Nitrile Butadiene Rubber

Hardness: 70 Shore A

Sales unit: 1 piece

The principal identification parameters are the 64 mm inside diameter, 1.5 mm cross-section, NBR material and 70 Shore A hardness.

O-Ring 64x1.5 Dimensions

The principal dimensions are:

Inside diameter ID: 64 mm

Cross-section CS: 1.5 mm

Outside diameter OD: 67 mm

Nominal dimensions: 64x1.5 mm

In the O-Ring designation 64x1.5, the first value represents the inside diameter and the second value represents the cross-section diameter.

The outside diameter is:

64 mm + 1.5 mm + 1.5 mm = 67 mm

Both nominal dimensions should be verified when selecting a replacement.

NBR Nitrile Butadiene Rubber

The sealing material is:

Material: NBR - Nitrile Butadiene Rubber

NBR is one of the most widely used elastomers in industrial sealing technology.

NBR O-rings are commonly used with many mineral oils, lubricating greases and other compatible technical media.

Exact compatibility depends on the specific medium, additives, temperature and actual operating conditions.

O-Ring NBR 70 Shore A

The hardness of this O-Ring is:

Hardness: 70 ShA

Hardness scale: Shore A

Material: NBR

The 70 Shore A hardness is an important part of the technical specification.

An O-Ring with identical 64x1.5 mm dimensions but a different hardness should not automatically be considered technically identical.

Dimensions, material and hardness should therefore be evaluated together.

O-Ring 64x1.5 NBR 70

The complete product identification is:

Dimensions: 64x1.5 mm

Material: NBR

Hardness: 70 ShA

Inside diameter: 64 mm

Cross-section: 1.5 mm

Outside diameter: 67 mm

This complete identification is more precise than searching only for an O-Ring 64x1.5 because the same nominal size can be available in different elastomers and hardness grades.

64 mm ID O-Ring with 1.5 mm Cross-Section

The nominal dimensions are:

Inside diameter ID: 64 mm

Cross-section CS: 1.5 mm

Outside diameter OD: 67 mm

The inside diameter and cross-section are the primary dimensional parameters used to identify an O-Ring.

Outside diameter alone is not sufficient to determine the correct O-Ring size.

O-Ring 64x1.5 NBR vs FKM

O-rings with identical dimensions can be manufactured from different elastomers.

This product: NBR 70 ShA

Alternative material: FPM/FKM

Dimensions: 64x1.5 mm

NBR and FPM/FKM belong to different elastomer families and should not automatically be considered materially interchangeable.

The appropriate material should be selected according to the medium and actual operating conditions.

O-Ring 64x1.5 for Technical Sealing

An O-Ring is a circular cross-section sealing element that creates a seal through controlled deformation when installed in a correctly designed groove.

O-rings are widely used in static sealing systems and can also be used in appropriately designed dynamic applications.

Suitability for a specific application depends on groove geometry, compression, medium, pressure, temperature and type of movement.

O-Ring 64x1.5 for Static Sealing

O-rings are commonly used as static sealing elements between components without relative movement at the sealing interface.

For proper sealing, the O-Ring must be matched to the groove geometry and mating surfaces.

The 64x1.5 mm dimensions, NBR material, 70 ShA hardness and operating conditions should all be considered during selection.

O-Ring 64x1.5 for Dynamic Sealing

O-rings can also be used in appropriately engineered dynamic sealing systems.

However, suitability for a particular dynamic application cannot be determined from dimensions and material alone.

Movement type, surface finish, lubrication, pressure, speed, groove design and actual operating conditions should also be considered.

How to Select a 64x1.5 NBR O-Ring

When selecting a corresponding O-Ring, verify:

• inside diameter 64 mm
• cross-section 1.5 mm
• material NBR
• hardness 70 ShA
• groove dimensions
• operating medium
• operating temperature
• pressure
• static or dynamic operation
• requirements of the specific sealing system

Matching the 64x1.5 mm dimensions alone does not establish complete technical interchangeability.

FAQ

What are the dimensions of the 64x1.5 NBR O-Ring?

Inside diameter ID: 64 mm

Cross-section CS: 1.5 mm

Outside diameter OD: 67 mm

What does 64x1.5 mean for an O-Ring?

The 64 mm value represents the inside diameter, while 1.5 mm represents the diameter of the circular cross-section.

What is the outside diameter of a 64x1.5 O-Ring?

The outside diameter is 67 mm.

What material is the 64x1.5 O-Ring made from?

Material: NBR - Nitrile Butadiene Rubber

What is the hardness of the 64x1.5 NBR O-Ring?

Hardness: 70 Shore A

What does 70 ShA mean?

70 ShA indicates the hardness of the elastomer measured on the Shore A scale.

Is the 64x1.5 NBR O-Ring resistant to oil?

NBR is widely used with many mineral oils and lubricating greases. Exact compatibility should be verified for the specific oil, additives, temperature and operating conditions.

Can an FKM 64x1.5 O-Ring replace an NBR 64x1.5 O-Ring?

Not automatically. Although the dimensions may be identical, NBR and FPM/FKM are different elastomer materials.

Can an O-Ring with a different hardness replace the 70 ShA version?

Not automatically. Hardness is an important technical parameter and should be verified for the specific application.

Is this O-Ring sold individually?

Yes. The sales unit is 1 piece.

How do I select a replacement for a 64x1.5 NBR 70 ShA O-Ring?

Verify the 64 mm inside diameter, 1.5 mm cross-section, NBR material, 70 ShA hardness, groove dimensions, operating medium and actual operating conditions.
