O-Ring 14x1.78 mm Dimensions

The designation 14x1.78 mm defines the two principal dimensions of the O-ring:

d1 - Inside diameter: 14 mm

d2 - Cross-section diameter: 1.78 mm

The nominal outside diameter can be calculated as:

14 mm + 2 x 1.78 mm = 17.56 mm

Complete nominal geometry:

Inside diameter d1: 14 mm

Cross-section d2: 1.78 mm

Nominal outside diameter: 17.56 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 criteria when selecting an O-ring.

An O-ring measuring 14x1.78 mm but manufactured from another elastomer or with a different hardness should not automatically be considered technically identical.

How Does a 14x1.78 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 on the O-ring dimensions, groove geometry, compression, elastomer material, operating medium and actual service conditions.

O-Ring NBR 14x1.78 mm - 1000 pcs Bulk Pack

This product page refers specifically to a bulk package containing:

1000 pcs

The 1000-piece format is intended primarily for customers who regularly use the same O-ring size in larger quantities.

The bulk package is particularly suitable for:

Industrial production

Manufacturing

MRO

Maintenance departments

Technical service companies

Workshops

Machine and equipment manufacturers

Industrial warehouses

B2B customers

It provides a larger stock of one defined 14x1.78 mm NBR 70 Shore A O-ring specification.

1000 pcs O-Rings for Industrial Production

Serial production may require the same O-ring size repeatedly during the assembly of machines, components or technical products.

A 1000-piece package provides a bulk supply of one specific configuration:

14x1.78 mm

NBR

70 Shore A

This format is suitable for maintaining stock for repetitive assembly and production processes.

Before use in production, the dimensions, elastomer and hardness should be verified against the technical documentation for the specific product or assembly.

NBR O-Rings for MRO and Maintenance

The 1000 pcs package is also suitable for MRO and maintenance departments that regularly consume 14x1.78 mm O-rings.

Maintaining a larger stock 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

Service conditions

NBR 14x1.78 mm 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

Additives

Temperature

Pressure

Exposure time

Operating conditions

Material compatibility should therefore be verified for the specific application.

NBR 14x1.78 O-Ring vs FKM, EPDM and VMQ

O-rings with identical 14x1.78 mm dimensions can be manufactured from different elastomers.

This product is specifically:

NBR 70 Shore A

An O-ring manufactured from FKM/FPM, EPDM, VMQ or another elastomer should not automatically be considered equivalent even if its nominal dimensions are identical.

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

How to Select a 14x1.78 mm O-Ring

When selecting an O-ring, verify at least:

Inside diameter d1: 14 mm

Cross-section d2: 1.78 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 14x1.78 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 14 mm and a cross-section diameter of 1.78 mm. Its nominal outside diameter is 17.56 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 measuring 14x1.78 mm.

Who is the 1000 pcs package intended for?

The bulk package is particularly suitable for industrial production, manufacturing, MRO, maintenance departments, technical service companies 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 14x1.78 FKM O-ring replace this NBR O-ring?

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

Are all 14x1.78 mm NBR O-rings identical?

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

What is the outside diameter of a 14x1.78 mm O-ring?

The nominal outside diameter is 17.56 mm, calculated as 14 + 2 x 1.78 mm.
