O-Ring 20x6 NBR 70 Shore A

O-ring 20x6 NBR 70 ShA - 100 pcs

O-ring 20x6 mm manufactured from NBR nitrile rubber with a nominal hardness of 70 Shore A. Supplied in a pack of 100 pcs. A standard circular-section sealing ring suitable for static and dynamic sealing applications where NBR is compatible with the operating medium and conditions.

O-ring NBR 20x6 - Technical Data

O-ring 20x6 mm Dimensions

The designation 20x6 mm means:

• inside diameter d1: 20 mm

• cross-section d2: 6 mm

• calculated outside diameter: 32 mm

The outside diameter is calculated as:

20 mm + 2 x 6 mm = 32 mm

When selecting an O-ring, both the inside diameter and cross-section must be verified.

NBR 70 Shore A

The O-ring is manufactured from NBR - nitrile butadiene rubber with a nominal hardness of 70 Shore A.

NBR is one of the most widely used elastomers for industrial sealing applications. It offers good resistance to many mineral oils and greases and is therefore commonly used in hydraulic, pneumatic and mechanical systems.

NBR is not universally resistant to all fluids and operating environments. Compatibility with the specific medium, temperature and operating conditions should always be verified before use.

Typical Applications

NBR 70 Shore A O-rings are widely used in:

• hydraulic systems

• pneumatic systems

• pumps

• valves

• cylinders

• gearboxes

• industrial machinery

• mechanical equipment

• pipe connections

• static sealing systems

• suitably designed dynamic sealing systems

Suitability of the 20x6 mm O-ring for a specific application depends on groove design, pressure, temperature, operating medium and type of movement.

How to Select an O-ring 20x6

Before ordering, verify:

1. Inside diameter - 20 mm.

2. Cross-section - 6 mm.

3. Material - NBR.

4. Hardness - 70 Shore A.

5. Operating medium.

6. Operating temperature.

7. Pressure.

8. Static or dynamic sealing application.

9. Groove dimensions and design.

Identical O-ring dimensions do not automatically mean identical suitability if the material, hardness or operating conditions differ.

FAQ

What are the dimensions of this O-ring?

The O-ring has an inside diameter of 20 mm and a cross-section of 6 mm, giving the size designation 20x6 mm.

What is the outside diameter of a 20x6 O-ring?

The calculated outside diameter is 32 mm.

What material is the O-ring made from?

The O-ring is manufactured from NBR - nitrile butadiene rubber.

What is the hardness?

The nominal hardness is 70 Shore A.

How many O-rings are included?

The pack contains 100 pcs.

Is NBR resistant to oil?

NBR provides good resistance to many mineral oils and greases. Compatibility should always be verified for the specific fluid and operating conditions.

Is the 20x6 NBR O-ring suitable for hydraulic systems?

NBR O-rings are widely used in hydraulic systems. Suitability of the 20x6 mm size depends on groove design, pressure, temperature, fluid and other operating conditions.

Can an NBR O-ring be replaced with FKM or EPDM?

The replacement should not be selected by dimensions alone. NBR, FKM and EPDM have different chemical and temperature resistance characteristics, so the elastomer must be selected according to the operating medium and conditions.
