O-Ring 22x5 NBR 70 Shore A 1000 pcs

O-Ring 22x5 NBR 70 Shore A 1000 pcs is a technical sealing ring with a 22 mm inside diameter, 5 mm cross-section diameter and nominal hardness of 70 Shore A. It is manufactured from NBR (Nitrile Butadiene Rubber). This product variant is supplied in a bulk pack of 1000 pieces.

In the 22x5 mm designation, 22 mm represents the inside diameter (d1), while 5 mm represents the cross-section diameter (d2).

O-Ring 22x5 NBR 70 Shore A - Product Characteristics

This O-ring has the conventional closed-ring geometry with a circular cross-section. Sealing is achieved by controlled compression of the elastomer between the mating surfaces.

The principal identification parameters of this exact product are:

Inside Diameter d1: 22 mm
Cross-Section Diameter d2: 5 mm
Material: NBR - Nitrile Butadiene Rubber
Nominal Hardness: 70 Shore A
Package Quantity: 1000 pcs

These parameters should be considered together when selecting or comparing the O-ring.

O-Ring 22x5 mm Dimensions

The designation 22x5 mm does not mean that the O-ring has a 22 mm outside diameter.

The dimensional notation is:

d1 = 22 mm - inside diameter
d2 = 5 mm - cross-section diameter

The theoretical outside diameter of an uninstalled O-ring can be calculated as:

22 + 2 x 5 = 32 mm

Therefore, the theoretical outside diameter is approximately 32 mm, subject to the applicable manufacturing tolerances.

NBR Material

NBR (Nitrile Butadiene Rubber) is an elastomer widely used for technical O-ring seals.

One of its important characteristics is compatibility with many mineral oils and mineral-based greases, which is why NBR is frequently used in industrial sealing systems.

However, NBR should not be treated as universally resistant to every fluid. Compatibility with the specific operating medium, temperature and application conditions should always be checked before installation.

70 Shore A Hardness

The nominal hardness of this O-ring is 70 ShA / 70 Shore A.

Hardness is an important technical selection parameter because it influences the deformation and compression behaviour of the elastomer. Two O-rings with identical 22x5 mm dimensions but different hardness values should not automatically be considered technically identical.

The complete identification of this variant is therefore:

22x5 mm -> NBR -> 70 Shore A -> 1000 pcs

How an O-Ring Provides Sealing

An O-ring is installed in a suitably dimensioned groove and compressed between mating surfaces. The deformation of its circular cross-section creates the sealing contact.

Correct performance therefore depends not only on the nominal 22x5 mm dimensions but also on the groove geometry, compression, operating pressure, medium, temperature and whether the application is static or involves movement.

These parameters should be evaluated for the specific sealing arrangement rather than assumed from the O-ring dimensions alone.

Pack of 1000 Pieces

This product page refers specifically to:

O-Ring 22x5 NBR 70 Shore A - 1000 pcs

The package quantity forms part of the commercial identification of this listing. It differentiates this product page from other quantities of the same 22x5 mm NBR 70 Shore A O-ring, including potential 100-piece packs.

This distinction also helps prevent search cannibalization between different package variants.

Technical Specification

Product: O-Ring / sealing ring
Dimensions: 22x5 mm
d1 - Inside Diameter: 22 mm
d2 - Cross-Section Diameter: 5 mm
Theoretical Outside Diameter: approx. 32 mm
Material: NBR - Nitrile Butadiene Rubber

Selection and Interchangeability

When selecting an equivalent, verify at least 22x5 mm dimensions, NBR material and 70 Shore A hardness.

Matching dimensions alone are insufficient if another O-ring uses a different elastomer or hardness. For a specific installation, the operating medium, temperature, pressure, type of movement and groove geometry should also be checked.

FAQ

What are the dimensions of the O-Ring 22x5 NBR 70 Shore A?
It has a 22 mm inside diameter and a 5 mm cross-section diameter.

What does 22x5 mean for an O-ring?
The first value is the inside diameter d1 = 22 mm. The second is the cross-section diameter d2 = 5 mm.

What is the outside diameter of a 22x5 O-ring?
The theoretical outside diameter is approximately 32 mm, calculated as 22 + 2 x 5 mm.

What material is this O-ring made from?
It is manufactured from NBR - Nitrile Butadiene Rubber.

What does 70 Shore A mean?
It specifies the nominal elastomer hardness of 70 on the Shore A scale.

Can NBR O-rings be used with oil?
NBR is commonly used with many mineral oils and mineral-based greases. Compatibility should still be checked for the specific fluid and operating conditions.

Are all 22x5 O-rings interchangeable?
No. In addition to dimensions, the elastomer material and hardness must be considered.

How many O-rings are included?
This specific product variant contains 1000 pieces.
