NBR O-Ring 22x2.62 mm 90 Shore A

Overview

The NBR O-Ring 22x2.62 mm 90 Shore A - 100 pcs is a professional industrial pack of high-hardness sealing rings designed for hydraulic systems, machinery maintenance, production and OEM applications.

Each O-ring is manufactured from NBR (Nitrile Butadiene Rubber) with an increased hardness of 90 Shore A. NBR provides very good resistance to mineral oils, lubricating greases and many conventional hydraulic fluids, making it one of the most widely used sealing materials in industrial equipment.

The 22 mm inside diameter, 2.62 mm cross-section and high-hardness compound make these seals particularly suitable for hydraulic components, pumps, valves, manifolds, fittings and machinery.

The 100-piece package provides a practical stock quantity for workshops, maintenance departments, industrial manufacturers and professional B2B customers.

Industrial Applications

The NBR 22x2.62 mm 90 Shore A O-Rings are suitable for:

• Hydraulic systems
• Hydraulic pumps
• Valves
• Hydraulic manifolds
• Fittings and adapters
• Hydraulic cylinders
• Pneumatic equipment
• Industrial machinery
• Agricultural equipment
• Construction machinery
• Maintenance and repair
• OEM assemblies

Construction

Each O-ring features an inside diameter of 22 mm and a 2.62 mm circular cross-section.

The precision circular profile provides uniform compression when installed in a correctly designed sealing groove.

The increased 90 Shore A hardness improves dimensional stability and reduces susceptibility to mechanical deformation compared with softer NBR compounds.

NBR Material

NBR (Nitrile Butadiene Rubber) is a widely used elastomer for industrial sealing applications, particularly where resistance to oils and lubricants is required.

NBR provides very good resistance to:

• Mineral oils
• Lubricating greases
• Many hydraulic fluids
• Numerous petroleum-based media
• Mechanical wear

Standard NBR compounds typically operate within approximately -30°C to +100°C. Actual temperature capability depends on the specific compound, operating medium and application conditions.

Why Choose NBR 90 Shore A?

The 90 Shore A compound is considerably harder than commonly used 70 Shore A NBR.

The increased hardness provides:

• Greater resistance to deformation
• Increased dimensional stability
• Improved extrusion resistance
• Reduced tendency to enter clearance gaps
• Good mechanical durability
• Reliable performance in demanding hydraulic applications

Why Choose a 100 pcs Pack?

The 100-piece pack of NBR 22x2.62 mm 90 Shore A O-rings is designed for professional users who regularly require the same seal size for servicing, assembly or production.

A 100 pcs package is particularly useful for:

• Maintenance departments
• Hydraulic service companies
• Machine manufacturers
• Repair workshops
• Industrial production
• Technical stockrooms
• OEM assembly
• Professional B2B buyers

Keeping 100 identical seals in stock reduces the need for frequent individual orders and simplifies maintenance inventory management.

NBR 90 Shore A vs NBR 70 Shore A

NBR 90 Shore A is significantly harder than standard NBR 70 Shore A.

The 90 Shore A version provides increased mechanical stability and greater resistance to extrusion under pressure.

NBR 70 Shore A is more flexible and conforms more easily to mating surfaces, making it widely used for conventional static sealing applications.

The appropriate hardness should always be selected according to system pressure, temperature, operating medium, groove geometry and sealing conditions.

Operational Advantages

• Professional package of 100 pcs.
• High 90 Shore A hardness.
• Very good resistance to mineral oils.
• Good resistance to lubricating greases.
• Increased mechanical stability.
• Improved extrusion resistance.
• Convenient stock quantity for maintenance departments.
• Suitable for production and OEM applications.

FAQ

How many O-rings are included in the package?

The package contains 100 O-rings.

What are the dimensions of each O-ring?

Each O-ring has an inside diameter of 22 mm and a cross-section of 2.62 mm.

What material are the O-rings made from?

They are manufactured from NBR (Nitrile Butadiene Rubber).

What is the hardness of the seals?

The material hardness is 90 Shore A.

Is NBR 90 Shore A harder than 70 Shore A?

Yes. 90 Shore A NBR is significantly harder and less susceptible to mechanical deformation.

Are these O-rings resistant to oil?

Yes. NBR provides very good resistance to many mineral oils.

Are they resistant to lubricating grease?

Yes. NBR is widely used with compatible industrial greases and lubricants.

Is the 22x2.62 mm O-ring suitable for hydraulic systems?

Yes. High-hardness NBR is commonly used in demanding hydraulic sealing applications.

Does 90 Shore A improve pressure resistance?

Higher hardness improves resistance to extrusion. Actual pressure capability also depends on groove geometry, extrusion gap, temperature, movement and the use of backup rings.

Can these O-rings be used in pumps?

Yes, provided NBR is chemically compatible with the operating medium and the sealing groove is designed for the specified dimensions.

Are they suitable for valves and hydraulic manifolds?

Yes. NBR O-rings are widely used in valves, manifolds, fittings and other hydraulic components.

Is the 100 pcs package suitable for serial production?

Yes. The 100-piece pack is a practical option for production, assembly, servicing, maintenance and OEM operations.

Is NBR suitable for hot water and steam?

Standard NBR is generally not the preferred material for prolonged hot water or steam exposure. EPDM is often more suitable for these applications.

Is NBR resistant to UV and ozone?

Standard NBR has limited resistance to prolonged UV radiation, ozone and weather exposure.

Can the NBR O-Ring 22x2.62 mm 90 Shore A replace an OEM seal?

Yes, provided its dimensions, material, hardness and operating parameters meet the original equipment manufacturer's requirements.
