O-Ring 9x1.5 NBR 70 Shore A

O-Ring 9x1.5 NBR 70 Shore A - 100 pcs

O-Ring 9x1.5 NBR 70 Shore A is a technical elastomeric sealing ring with a 9 mm inside diameter and 1.5 mm cross-section. It is manufactured from NBR - Nitrile Butadiene Rubber with a nominal hardness of 70 Shore A. Its circular cross-section allows controlled compression in an appropriately designed sealing groove. This package contains 100 pcs.

O-Ring 9x1.5 mm Dimensions

The principal dimensions are:

ID = 9 mm - inside diameter

CS = 1.5 mm - cross-section diameter

OD = 12 mm - calculated nominal outside diameter

The O-ring size is specified as:

ID x CS = 9x1.5 mm

The nominal outside diameter can be calculated using:

OD = ID + 2 x CS

For this size:

9 + (2 x 1.5) = 12 mm

The ID and CS are the primary dimensional parameters used to identify the O-ring.

NBR - Nitrile Butadiene Rubber

The O-ring is manufactured from:

NBR - Nitrile Butadiene Rubber

NBR is a widely used elastomer in sealing technology.

When selecting an O-ring for a specific application, the material should be evaluated against the working medium and actual operating conditions.

The NBR designation alone does not define all operating limits because the exact properties also depend on the specific elastomer compound.

70 Shore A Hardness

The nominal hardness of this O-ring is:

70 Shore A

also written as:

70 ShA

Hardness is an important parameter in the technical specification of an elastomeric sealing ring.

The basic identification of this product is therefore:

9x1.5 + NBR + 70 Shore A

An O-ring with the same dimensions but a different material or hardness is a different technical variant.

How Does an O-Ring Work?

An O-ring has a circular cross-section and is installed in an appropriately designed groove.

When the mating components are assembled, the elastomer is compressed in a controlled manner. This deformation creates contact between the O-ring and the sealing surfaces.

Correct sealing performance depends on factors including:

O-ring dimensions

groove geometry

compression

elastomer material

hardness

working medium

operating conditions

For this reason, the O-ring should be selected as part of the complete sealing arrangement rather than by dimensions alone.

Typical Applications of NBR O-Rings

NBR O-rings are commonly used as sealing elements in:

hydraulic systems

pneumatic systems

pumps

valves

cylinders

technical fittings

industrial machinery

mechanical equipment

maintenance and repair

MRO applications

The suitability of the exact 9x1.5 NBR 70 Shore A specification should always be verified against the requirements of the specific sealing application.

How to Select O-Ring 9x1.5 NBR

Before ordering, verify four primary parameters:

ID - 9 mm

CS - 1.5 mm

Material - NBR

Hardness - 70 Shore A

The groove geometry, working medium and actual operating conditions should also be considered.

A used O-ring may be stretched, flattened or permanently deformed, so measurements taken from an old seal may differ from its original nominal dimensions.

O-Ring 9x1.5 Interchangeability

Matching 9x1.5 mm dimensions alone do not confirm complete interchangeability.

A potential replacement should also be compared for:

inside diameter ID

cross-section CS

elastomer material

hardness

application requirements

An FKM, EPDM or VMQ O-ring 9x1.5 mm has a different material specification from an NBR 9x1.5 mm O-ring.

FAQ - O-Ring 9x1.5 NBR 70 Shore A

What does 9x1.5 mm mean?

9 mm is the nominal inside diameter ID, while 1.5 mm is the cross-section diameter CS.

What is the outside diameter of this O-ring?

The calculated nominal outside diameter is 12 mm.

What material is this O-ring made from?

It is manufactured from NBR - Nitrile Butadiene Rubber.

What does 70 Shore A mean?

It is the nominal hardness of the elastomer measured on the Shore A hardness scale.

Are all 9x1.5 mm O-rings the same?

No. In addition to dimensions, material and hardness must be considered. This product is specified as 9x1.5 NBR 70 Shore A.

Can an FKM or EPDM 9x1.5 O-ring be considered the same product?

No. FKM, EPDM and NBR are different elastomer materials. Matching dimensions alone do not make them the same technical variant.

How should a replacement O-ring be selected?

Verify the 9 mm ID, 1.5 mm CS, NBR material and 70 Shore A hardness, together with the requirements of the specific sealing application.

How many O-rings are included?

The package contains 100 pcs.
