O-Ring 63x1.5 NBR 70 ShA GRN

O-Ring 63x1.5 NBR 70 ShA GRN

GRN O-Ring 63x1.5 NBR 70 ShA is a circular cross-section sealing ring manufactured from nitrile rubber.

Brand: GRN

Reference: 63X1.5

Product type: O-Ring

Dimensions: 63x1.5 mm

Inside diameter ID: 63 mm

Cross-section CS: 1.5 mm

Calculated outside diameter OD: 66 mm

Material: NBR - Nitrile Butadiene Rubber

Hardness: 70 Shore A

Sales unit: 1 piece

The principal identification parameters are the 63 mm inside diameter, 1.5 mm cross-section, NBR material and 70 ShA hardness.

O-Ring 63x1.5 Dimensions

The principal dimensions are:

Inside diameter ID: 63 mm

Cross-section CS: 1.5 mm

Calculated outside diameter OD: 66 mm

Nominal dimensions: 63x1.5 mm

In the O-Ring designation 63x1.5, the first value represents the inside diameter and the second value represents the cross-section diameter.

The outside diameter is calculated as:

63 mm + 1.5 mm + 1.5 mm = 66 mm

Both the inside diameter and cross-section 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 should always be checked for 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 the same 63x1.5 mm dimensions but a different hardness should not automatically be considered technically identical.

Dimensions, material and hardness should therefore be considered together when selecting a corresponding seal.

O-Ring 63x1.5 NBR 70

The complete product identification is:

Dimensions: 63x1.5 mm

Material: NBR

Hardness: 70 ShA

Inside diameter: 63 mm

Cross-section: 1.5 mm

Calculated outside diameter: 66 mm

This complete identification is more precise than searching only for an O-Ring 63x1.5, because O-rings with the same dimensions can be manufactured from different elastomers and with different hardness levels.

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

The nominal dimensions are:

Inside diameter ID: 63 mm

Cross-section CS: 1.5 mm

Calculated outside diameter OD: 66 mm

For O-Ring identification, the inside diameter and cross-section are the primary dimensional parameters.

The outside diameter alone is not sufficient to identify the correct O-Ring size.

O-Ring 63x1.5 NBR vs FKM

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

This product: NBR 70 ShA

Alternative material: FPM/FKM

Dimensions: 63x1.5 mm

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

The correct sealing material should be selected according to the operating medium and actual application requirements.

O-Ring 63x1.5 for Technical Sealing

An O-Ring is a circular cross-section sealing element designed to create a seal through controlled deformation when installed in an appropriately designed groove.

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

Suitability for a particular application depends on factors including groove geometry, compression, operating medium, pressure, temperature and type of movement.

O-Ring 63x1.5 for Static Sealing

O-rings are commonly used as static sealing elements between components where relative movement at the sealing interface is absent.

For a static application, the O-Ring must be correctly matched to the groove and mating surfaces.

The 63x1.5 mm dimensions, NBR 70 ShA material specification, groove geometry and operating conditions should all be considered during selection.

O-Ring 63x1.5 for Dynamic Sealing

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

However, the suitability of this O-Ring for a specific dynamic application cannot be determined from dimensions and material alone.

The type of movement, surface finish, lubrication, pressure, speed, groove design and operating conditions must also be considered.

How to Select a 63x1.5 NBR O-Ring

When selecting a corresponding O-Ring, verify:

• inside diameter 63 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 63x1.5 mm dimensions alone does not establish complete technical interchangeability.

FAQ

What are the dimensions of the 63x1.5 NBR O-Ring?

Inside diameter ID: 63 mm

Cross-section CS: 1.5 mm

Calculated outside diameter OD: 66 mm

What does 63x1.5 mean for an O-Ring?

The 63 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 63x1.5 O-Ring?

The calculated outside diameter is 66 mm.

What material is the 63x1.5 O-Ring made from?

Material: NBR - Nitrile Butadiene Rubber

What is the hardness of the 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 63x1.5 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 63x1.5 O-Ring replace an NBR 63x1.5 O-Ring?

Not automatically.

Although the dimensions may be identical, NBR and FKM/FPM are different elastomer materials. Material compatibility should be verified for the specific application.

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

Not automatically. Hardness is an important technical parameter and can influence sealing behaviour.

The required hardness should be verified for the specific application.

Is the O-Ring sold individually?

Yes. The sales unit is 1 piece.

How do I select a replacement for a 63x1.5 NBR 70 ShA O-Ring?

Verify the 63 mm inside diameter, 1.5 mm cross-section, NBR material, 70 ShA hardness, groove dimensions, operating medium and actual operating conditions.
