O-Ring NBR 19.2x3 mm 70 Shore A

Product Overview

O-Ring NBR 19.2x3 mm 70 Shore A - 1000 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 19.2 mm and a cross-section of 3 mm. NBR is one of the most widely used elastomers in industrial sealing technology due to its good resistance to many mineral oils, lubricating greases and compatible technical fluids.

The 1000-piece bulk pack is particularly suitable for serial production, OEM assembly, industrial maintenance, technical distribution and B2B purchasing.

NBR 70 Shore A Material

NBR (Nitrile Butadiene Rubber) is widely used for O-rings in hydraulic, pneumatic and general industrial sealing systems.

Typical properties include:

• good resistance to many mineral oils
• good resistance to lubricating greases
• good mechanical strength
• good wear resistance
• useful elasticity
• broad industrial applicability

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

O-Ring 19.2x3 mm Dimensions

The nominal dimensions are:

Inside Diameter: 19.2 mm
Cross-Section: 3 mm
Outside Diameter: Approximately 25.2 mm
Material: NBR
Hardness: 70 Shore A
Pack Quantity: 1000 pcs

The designation 19.2x3 mm refers to the inside diameter and cross-section of the O-ring. Both dimensions should be verified when selecting a replacement seal.

Industrial Applications

NBR 19.2x3 mm O-rings can be used in appropriately designed sealing systems for:

• hydraulic systems
• pneumatic systems
• pumps
• valves
• industrial fittings
• oil systems
• industrial machinery
• production equipment
• technical installations
• mechanical assemblies

They can be used in static sealing arrangements and in suitably designed dynamic applications.

1000-Piece Bulk Pack for Production and B2B

The 1000 pcs pack of NBR 19.2x3 O-rings is intended for professional customers requiring this dimension in larger quantities.

The bulk pack is particularly suitable for:

• serial production
• OEM manufacturing
• industrial assembly
• manufacturing plants
• maintenance departments
• machine builders
• technical service companies
• industrial distributors
• B2B procurement

A standardized 1000-piece pack supports efficient inventory management and continuous supply for repetitive production and maintenance operations.

How to Select an O-Ring 19.2x3

Correct O-ring selection should consider:

• 19.2 mm inside diameter
• 3 mm cross-section
• NBR sealing material
• 70 Shore A hardness
• operating medium
• temperature
• pressure
• groove dimensions
• static or dynamic operation

An O-ring with identical 19.2x3 mm dimensions manufactured from FKM, EPDM or MVQ may have significantly different chemical, thermal and mechanical properties.

Operational Advantages

• Precise 19.2x3 mm dimensions.
• NBR sealing material.
• Nominal hardness of 70 Shore A.
• Good resistance to many mineral oils.
• Good resistance to lubricating greases.
• Practical 1000-piece bulk pack for production and B2B.

FAQ

What are the dimensions of the NBR 19.2x3 O-ring?

The O-ring has a 19.2 mm inside diameter and 3 mm cross-section. Its calculated outside diameter is approximately 25.2 mm.

How many O-rings are included in the package?

The package contains 1000 pieces of NBR 19.2x3 mm 70 Shore A 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 the NBR 19.2x3 O-ring resistant to oil?

NBR provides good resistance to many mineral oils and lubricating greases, making it widely used in oil-related industrial sealing systems. Compatibility should always be checked for the specific fluid.

Can the 19.2x3 O-ring be used in hydraulic systems?

NBR 70 Shore A is commonly used in hydraulic sealing applications. Actual suitability depends on the medium, pressure, temperature, groove geometry and operating conditions.

What does the 19.2x3 mm size mean?

The first value, 19.2 mm, is the inside diameter, while 3 mm is the cross-section diameter. The nominal outside diameter is approximately 25.2 mm.

Why choose the 1000-piece pack?

The 1000-piece bulk pack is designed primarily for serial production, OEM manufacturing, industrial maintenance, distributors and B2B customers that regularly consume this O-ring size.

Can an FKM 19.2x3 O-ring replace this NBR version?

Not automatically. Although the dimensions may be identical, FKM and NBR have different chemical and thermal properties. The sealing material must be selected according to the actual operating conditions.
