O-Ring 15.3x2.4 mm Dimensions

The designation 15.3x2.4 mm defines the two principal O-ring dimensions:

d1 - Inside diameter: 15.3 mm

d2 - Cross-section diameter: 2.4 mm

The nominal outside diameter can be calculated as:

15.3 mm + 2 x 2.4 mm = 20.1 mm

Complete nominal geometry:

Inside diameter d1: 15.3 mm

Cross-section d2: 2.4 mm

Nominal outside diameter: 20.1 mm

Both the inside diameter and cross-section should be verified when selecting an O-ring.

What Does NBR 70 Shore A Mean?

NBR stands for:

Nitrile Butadiene Rubber

The nominal hardness of this O-ring is:

70 Shore A

Material and hardness are important technical selection criteria.

An O-ring measuring 15.3x2.4 mm but manufactured from another elastomer or with a different hardness should not automatically be considered technically identical.

How Does a 15.3x2.4 mm O-Ring Work?

An O-ring is a closed elastomer sealing ring with a round cross-section.

When installed in a correctly designed groove, the O-ring cross-section is compressed between the mating surfaces.

The resulting deformation of the elastomer creates the sealing interface.

Effective sealing depends not only on the O-ring itself but also on groove geometry, compression, material, operating conditions and the mating surfaces.

O-Ring NBR 15.3x2.4 mm - 1000 pcs Bulk Pack

This product page refers specifically to a bulk package containing:

1000 pcs

The 1000-piece format is particularly suitable for customers who regularly use the same O-ring size in larger quantities, including:

Industrial production

Manufacturing

MRO

Maintenance departments

Technical service companies

Machine and equipment manufacturers

Workshops

Industrial warehouses

B2B customers

The bulk package provides a larger stock of one specific 15.3x2.4 mm NBR 70 Shore A size.

1000 pcs O-Rings for Industrial Production

Production processes may require the same O-ring size repeatedly during the assembly of machines, components or other technical products.

A 1000-piece package provides a bulk supply of one defined specification:

15.3x2.4 mm

NBR

70 Shore A

For serial production, the required material specification and dimensional requirements should always be verified against the technical documentation for the manufactured component or assembly.

O-Rings for MRO and Maintenance Stock

The 1000 pcs package can also be used as technical warehouse stock for maintenance and MRO departments where 15.3x2.4 mm O-rings are consumed regularly.

Maintaining a larger quantity of one specific size can reduce the need for frequent replenishment.

Before installation, verify the required:

Dimensions

Material

Hardness

Operating medium

Temperature

Pressure

Groove geometry

Application requirements

NBR O-Rings and Oils

NBR is commonly used in sealing applications involving many compatible mineral oils and lubricating greases.

However, NBR should not be considered universally compatible with every oil, fuel or chemical medium.

Exact compatibility depends on factors including:

Type of medium

Chemical composition and additives

Temperature

Pressure

Exposure time

Operating conditions

Material compatibility should therefore be verified for the specific application.

NBR 15.3x2.4 O-Ring vs Other Materials

The 15.3x2.4 mm dimensions do not define the elastomer material.

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

This product is specifically:

NBR 70 Shore A

If the equipment specification requires FPM/FKM, EPDM, VMQ or another material, an NBR O-ring should not automatically be used as a replacement solely because the dimensions match.

How to Select a 15.3x2.4 mm O-Ring

When selecting an O-ring, verify at least:

Inside diameter d1: 15.3 mm

Cross-section d2: 2.4 mm

Material: NBR

Nominal hardness: 70 Shore A

Groove dimensions

Required compression

Operating medium

Operating temperature

Pressure

Static or dynamic sealing conditions

Equipment manufacturer's technical requirements

Matching the 15.3x2.4 mm dimensions alone does not establish complete technical interchangeability.

FAQ

What are the dimensions of this O-Ring?

The O-ring has an inside diameter of 15.3 mm and a cross-section diameter of 2.4 mm. Its nominal outside diameter is 20.1 mm.

What does NBR 70 Shore A mean?

NBR stands for Nitrile Butadiene Rubber. 70 Shore A specifies the nominal hardness of the elastomer.

How many O-rings are included in the package?

This bulk package contains 1000 O-rings.

Who is the 1000 pcs package intended for?

The bulk package is particularly suitable for industrial production, MRO, maintenance departments, technical service companies, workshops and warehouse stock where the same O-ring size is regularly required.

Can NBR O-rings be used with oil?

NBR is commonly used with many compatible mineral oils and lubricating greases. Exact compatibility depends on the specific medium, additives, temperature and operating conditions.

Can a 15.3x2.4 FPM O-ring replace this NBR O-ring?

Not automatically. FPM and NBR are different elastomers with different material properties. The required material should be verified for the specific application.

Are all 15.3x2.4 NBR O-rings identical?

No. In addition to dimensions and elastomer type, hardness and the required material specification should be considered.

What is the outside diameter of a 15.3x2.4 mm O-ring?

The nominal outside diameter is 20.1 mm, calculated as 15.3 + 2 x 2.4 mm.
