O-Ring NBR 10.77x2.62 mm 70 Shore A

Product Overview

O-Ring NBR 10.77x2.62 mm 70 Shore A - 100 pcs is a bulk pack of industrial sealing rings manufactured from NBR (Nitrile Butadiene Rubber) with a nominal hardness of 70 Shore A.

Each O-ring has an inside diameter of 10.77 mm and a 2.62 mm cross-section. NBR is widely used in industrial sealing technology because of its good resistance to many mineral oils, lubricating greases and compatible technical fluids.

The 100-piece pack is particularly suitable for maintenance departments, workshops, machine manufacturers, production facilities and B2B customers requiring this size for regular service or production use.

NBR 70 Shore A Sealing Material

NBR - Nitrile Butadiene Rubber is one of the most commonly used elastomers for industrial O-rings.

Typical properties include:

• good resistance to many mineral oils
• good resistance to lubricating greases
• useful mechanical strength
• good wear resistance
• good elasticity
• wide use in hydraulic and industrial sealing systems

Chemical compatibility should always be verified for the specific fluid, temperature and operating conditions.

O-Ring 10.77x2.62 mm Dimensions

The nominal dimensions of each O-ring are:

Inside Diameter: 10.77 mm
Cross-Section: 2.62 mm
Outside Diameter: Approximately 16.01 mm
Material: NBR
Hardness: 70 Shore A
Pack Quantity: 100 pcs

Both the 10.77 mm inside diameter and 2.62 mm cross-section should be verified when selecting a replacement.

Industrial Applications

NBR 10.77x2.62 mm O-rings can be used in appropriately designed sealing systems for:

• hydraulic systems
• pneumatic equipment
• pumps
• valves
• industrial fittings
• machinery
• oil systems
• technical equipment
• machine components
• maintenance and repair operations

Suitability depends on the medium, pressure, temperature, groove geometry and whether the sealing application is static or dynamic.

100-Piece Pack for B2B and Maintenance

The 100 pcs pack of 10.77x2.62 NBR O-rings is intended for customers who regularly use this specific size.

It is particularly practical for:

• industrial maintenance departments
• manufacturing plants
• machine builders
• technical workshops
• repair services
• OEM production
• industrial distributors
• B2B purchasing

Keeping a standardized 100-piece pack in maintenance inventory can simplify replacement and stock management for frequently serviced equipment.

Technical Specification

How to Select the Correct O-Ring

Correct selection requires more than matching the nominal dimensions.

Verify:

• 10.77 mm inside diameter
• 2.62 mm cross-section
• NBR sealing material
• 70 Shore A hardness
• operating medium
• temperature
• pressure
• groove dimensions
• static or dynamic operating conditions

An O-ring with the same dimensions but manufactured from a different elastomer may not provide equivalent sealing performance.

Operational Advantages

• Precise 10.77x2.62 mm dimensions.
• NBR sealing material.
• Nominal hardness of 70 Shore A.
• Good resistance to many mineral oils and greases.
• Suitable for many hydraulic and industrial applications.
• Practical 100-piece pack for B2B, maintenance and production use.

FAQ

What are the dimensions of this NBR O-ring?

Each O-ring has a 10.77 mm inside diameter and 2.62 mm cross-section. The approximate outside diameter is 16.01 mm.

How many O-rings are included in the pack?

The package contains 100 pieces of NBR 10.77x2.62 mm O-rings.

What does NBR 70 Shore A mean?

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

Is NBR 10.77x2.62 suitable for oil?

NBR provides good resistance to many mineral oils and lubricating greases, which is why it is widely used in oil-related industrial sealing applications. Compatibility should still be verified for the specific fluid.

Can this O-ring be used in hydraulic systems?

NBR 70 Shore A is commonly used in hydraulic sealing applications. Pressure, fluid, temperature, groove design and operating conditions must be considered when selecting the seal.

Does 10.77x2.62 mm specify the outside diameter?

No. 10.77 mm is the inside diameter and 2.62 mm is the cross-section diameter. The calculated outside diameter is approximately 16.01 mm.

Can an O-ring of the same size but a different material be used instead?

Not automatically. NBR, FKM, EPDM and MVQ have different chemical and thermal properties. Material compatibility is as important as the dimensions.
