O-Ring NBR 22.3x2.4 mm 70 Shore A - 1000 pcs

O-Ring NBR 22.3x2.4 mm 70 Shore A - 1000 pcs

O-Ring NBR 22.3x2.4 mm 70 Shore A - 1000 pcs is a bulk package of elastomer sealing rings with a 22.3 mm inside diameter and 2.4 mm cross-section. The O-rings are manufactured from NBR - Nitrile Butadiene Rubber with a nominal hardness of 70 Shore A. This industrial pack contains 1000 pieces for production, maintenance, service and regular B2B requirements.

O-Ring NBR 22.3x2.4 - Dimensions

d1 - Inside diameter: 22.3 mm
s - Cross-section: 2.4 mm
Nominal outside diameter: 27.1 mm
Size: 22.3x2.4 mm
Material: NBR
Hardness: 70 Shore A
Pack quantity: 1000 pcs

The size designation:

22.3x2.4 mm

means:

22.3 mm - inside diameter

2.4 mm - cross-section diameter

The nominal outside diameter is:

22.3 + 2 x 2.4 = 27.1 mm

NBR 70 Shore A Material

The O-rings are manufactured from:

NBR - Nitrile Butadiene Rubber

with a nominal hardness of:

70 Shore A

NBR is one of the most widely used elastomers in technical sealing applications and is compatible with many common mineral oils and lubricating greases.

Compatibility must always be checked against the actual operating medium, temperature and application conditions.

What Does 70 Shore A Mean?

70 Shore A specifies the nominal hardness of the elastomer.

Hardness is an important selection parameter because it affects the deformation of the O-ring after installation in the groove.

The complete technical identification is therefore:

22.3x2.4 mm + NBR + 70 Shore A

An O-ring with the same dimensions but a different material or hardness should not automatically be considered equivalent.

Bulk Pack of 1000 O-Rings

This product contains:

1000 O-Rings 22.3x2.4 NBR 70 Shore A

The bulk quantity is intended for applications where the same O-ring size is consumed regularly.

A 1000-piece package is particularly suitable for:

industrial production
maintenance departments
technical service operations
workshops
spare parts inventories
B2B purchasing

It reduces the need for frequent replenishment when 22.3x2.4 mm O-rings are used repeatedly.

How Does an O-Ring Work?

An O-ring is an elastomer sealing element with a circular cross-section.

The sealing function is created by controlled compression of the O-ring between mating surfaces.

Seal performance depends on several factors, including:

groove geometry
O-ring compression
surface condition
operating medium
temperature
pressure
type of movement

For this reason, the O-ring size alone does not define all permissible operating conditions.

How to Select a 22.3x2.4 O-Ring

When selecting a replacement, verify:

Inside diameter: 22.3 mm
Cross-section: 2.4 mm
Material: NBR
Hardness: 70 Shore A

The material must also be compatible with the operating medium and actual working conditions.

For industrial use of a 1000-piece pack, confirming the exact nominal size before ordering is particularly important.

22.3x2.4 vs Similar O-Ring Sizes

O-rings with dimensions close to 22.3x2.4 mm may look very similar but should not automatically be considered interchangeable.

Even a small difference in inside diameter or cross-section can affect:

O-ring stretch

compression in the groove

positioning

and ultimately:

sealing performance

A used O-ring may also be stretched or permanently deformed, so measurements should be compared with the nominal size specified for the installation.

1000 pcs vs 100 pcs Pack

This product is the 1000-piece industrial pack.

A separate 100-piece variant is intended for lower-volume requirements.

Although both quantity variants can use the same technical O-ring specification, they serve different purchasing needs.

The 1000 pcs version is focused on:

bulk purchasing
industrial supply
production requirements
maintenance stock
regular B2B consumption

FAQ

What are the dimensions of the O-Ring NBR 22.3x2.4?

The O-ring has a 22.3 mm inside diameter and 2.4 mm cross-section.

What is the outside diameter of a 22.3x2.4 O-Ring?

The nominal outside diameter is 27.1 mm.

What does NBR 70 Shore A mean?

NBR means Nitrile Butadiene Rubber, while 70 Shore A specifies the nominal hardness of the elastomer.

How many O-rings are included in the package?

This bulk package contains 1000 pieces.

Who is the 1000 pcs pack intended for?

The bulk pack is intended primarily for industrial production, maintenance, technical service, workshops and B2B customers with regular demand for this size.

Is NBR suitable for oil?

NBR is compatible with many common mineral oils and lubricating greases. Compatibility should always be verified for the specific medium and operating conditions.

Does 22.3x2.4 mean inside and outside diameter?

No. 22.3 mm is the inside diameter and 2.4 mm is the cross-section diameter. The resulting nominal outside diameter is 27.1 mm.

Can a similar O-ring size replace 22.3x2.4?

Not automatically. Changes in inside diameter or cross-section can affect stretch and compression in the groove and therefore sealing performance.
