O-Ring NBR 15x3 mm 70 ShA

Overview

O-Ring NBR 15x3 mm 70 ShA (1000 pcs) is an industrial bulk pack containing 1000 GRN sealing rings. Each O-ring has a 15 mm inside diameter and 3 mm circular cross-section. NBR with a nominal hardness of 70 Shore A is widely used in technical sealing systems involving compatible mineral oils, greases and industrial fluids.

Industrial Applications

O-Ring NBR 15x3 mm can be used in appropriately designed static sealing points in fittings, housings, covers, hydraulic assemblies and industrial machinery. The 1000-piece bulk pack is intended primarily for serial production, maintenance departments, industrial service, machine rebuilding and B2B buyers requiring regular quantities of the same sealing specification.

Construction

The O-ring is a one-piece elastomer seal with a 3 mm circular cross-section. It has no sealing lip, garter spring or separate dust lip. Sealing is generated through controlled compression of the elastomer inside a correctly designed groove. Pressure capability depends on groove geometry, extrusion gap, operating medium and actual service conditions.

Material

NBR, Nitrile Butadiene Rubber, provides good mechanical properties and compatibility with many mineral oils, greases and compatible hydraulic fluids. This version has a nominal hardness of 70 ShA. Temperature capability depends on the specific NBR compound, therefore a universal temperature range should not be assigned without verified compound data.

Why Industrial Buyers Choose This Product

O-Ring NBR 15x3 mm 70 ShA in a 1000-piece bulk pack supports production supply, maintenance stock, industrial service and machine rebuilding where regular consumption of one size is required. The bulk quantity reduces replenishment frequency. For OEM replacement or fleet maintenance, dimensions, material, hardness, tolerances and operating conditions should be checked against the original sealing specification.

Operational Advantages

• 1000-piece bulk packaging supports regular industrial consumption.
• 15x3 mm dimensions provide clear sealing ring identification.
• NBR is compatible with many mineral oils and greases.
• 70 Shore A defines the nominal elastomer hardness.
• One-piece construction requires no spring or additional sealing component.
• Bulk supply supports serial production and technical inventory management.

FAQ

What does O-Ring NBR 15x3 mm mean?

15 mm is the nominal inside diameter, while 3 mm is the diameter of the circular cross-section.

How many 15x3 O-rings are included in the package?

The bulk package contains 1000 O-Ring NBR 15x3 mm 70 ShA sealing rings with the same nominal specification.

What is the outside diameter of O-Ring 15x3?

The nominal outside diameter is 21 mm, calculated as 15 + 2 x 3 mm. The commercial O-ring size remains 15x3 mm.

Who is the 1000-piece bulk pack intended for?

The bulk format is intended primarily for serial production, maintenance departments, industrial service, technical distributors and other B2B customers with higher consumption.

Can NBR 70 ShA be replaced with another elastomer?

Not automatically. FKM, EPDM, VMQ and other elastomers may have the same 15x3 mm dimensions but different chemical, thermal and operating characteristics.
