O-Ring NBR 8x4 mm 70 ShA

O-Ring NBR 8x4 mm 70 ShA Bulk Pack of 1000 pcs

O-Ring NBR 8x4 mm 70 ShA - 1000 pcs is a bulk industrial pack of sealing rings designed for companies requiring larger quantities of one specific O-ring size. Each O-ring has an inside diameter of 8 mm, a cross-section of 4 mm and a hardness of 70 Shore A.

The 1000 pcs bulk pack is intended for serial production, OEM manufacturing, industrial plants, MRO departments, workshops, resellers and technical inventories. Keeping a larger quantity of one size in stock helps maintain continuity of production and reduces the need for frequent replenishment orders.

Serial Production and Industrial Use

O-Ring NBR 8x4 mm 70 ShA combines an 8 mm inside diameter with a relatively substantial 4 mm cross-section. When correctly matched to the groove and operating parameters, it can be used as a sealing component in various technical assemblies.

The 1000-piece package is particularly suitable where the same O-ring size is repeatedly consumed during manufacturing, assembly, maintenance or repair operations.

Typical application areas include:

• Hydraulic systems
• Pneumatic systems
• Pumps and valves
• Industrial machinery
• Mechanical assemblies
• Production equipment
• Technical installations
• Maintenance and repair operations

Final O-ring selection should consider the medium, temperature, pressure, groove geometry and actual operating conditions.

Benefits of Buying 1000 pcs in Bulk

A 1000 pcs bulk pack of O-Ring NBR 8x4 mm 70 ShA provides a practical supply format for professional users with regular demand for this specific size.

For manufacturers, a larger package can support multiple production batches. MRO departments can maintain a dedicated replacement inventory, while distributors and resellers can use the bulk pack to replenish their technical sealing stock.

Bulk purchasing also helps reduce the frequency of replenishment orders and simplifies inventory planning for frequently consumed sealing components.

Why NBR 70 ShA

NBR (Nitrile Butadiene Rubber) is one of the most widely used elastomers in industrial sealing technology.

It provides good resistance to many mineral oils, lubricating greases and compatible technical fluids. 70 Shore A is a commonly used hardness that provides a practical balance between elasticity and mechanical properties for many general industrial sealing applications.

Material compatibility should always be verified for the specific fluid and operating environment.

Warehouse Stock and B2B Logistics

The O-Ring NBR 8x4 mm 70 ShA - 1000 pcs bulk package can be maintained as operational inventory for continuous production, industrial maintenance, workshops and technical warehouses.

O-rings should be stored under appropriate conditions and protected from direct sunlight, excessive heat, ozone and other factors that may accelerate elastomer ageing.

Clear identification by NBR material, 8x4 mm dimensions and 70 ShA hardness simplifies inventory control and reduces the risk of selecting an incorrect sealing component.
