Why NBR 70 ShA for Industrial Sealing?

NBR, nitrile butadiene rubber, is one of the most established elastomers used in industrial sealing technology. Its good resistance to many mineral oils and lubricating greases makes it suitable for hydraulic, pneumatic and general mechanical applications.

The 70 Shore A hardness provides a practical balance between elasticity and mechanical stability. It is widely used for general-purpose O-rings installed in correctly designed sealing grooves.

Serial Applications of 14x2.5 O-Rings

The 14x2.5 mm O-ring can be used in appropriately designed:

• hydraulic systems
• pneumatic equipment
• valves and manifolds
• pumps
• technical fittings
• oil-lubricated assemblies
• industrial machinery
• production equipment
• OEM components
• maintenance operations

Final selection should consider groove geometry, pressure, temperature, operating medium and whether the seal operates under static or dynamic conditions.

1000 pcs Bulk Pack for OEM Production

The 1000 pcs package is designed for companies that repeatedly consume the same O-ring size.

In serial manufacturing, bulk packaging allows sealing rings to be maintained directly as production line stock or central component inventory.

This format is particularly suitable for machinery manufacturers, component producers, industrial assembly plants and OEM suppliers where the 14x2.5 mm O-ring is used as a recurring production component.

Economic Benefits of Bulk Purchasing

Purchasing 1000 identical O-rings can reduce the frequency of small replenishment orders and simplify internal material logistics.

For B2B users, bulk stock can support:

• repetitive OEM assembly
• production line replenishment
• multiple maintenance workstations
• planned overhaul programs
• industrial warehouse stock
• reseller inventory
• continuity of production

For regularly consumed sealing sizes, maintaining a larger quantity on site can reduce the risk of production or maintenance delays caused by shortages of small technical components.

Hydraulic Applications

NBR is widely used in hydraulic sealing systems, especially with compatible mineral oil-based hydraulic fluids.

A 14x2.5 mm O-ring can be used in correctly designed hydraulic connections, valves, manifolds and other components requiring compact elastomeric sealing.

For higher-pressure systems, groove dimensions, extrusion gaps and the possible requirement for backup rings should also be considered.

Pneumatic Applications

NBR O-rings are also commonly used in pneumatic systems.

Depending on the sealing arrangement, the 14x2.5 mm size may be used in valves, connectors, pneumatic components and other assemblies operating with compressed air.

In dynamic applications, surface condition, lubrication and friction should be considered during seal selection.

MRO and Maintenance Stock

A 1000 pcs stock of NBR 14x2.5 O-rings is particularly useful for maintenance departments where the same sealing dimension appears repeatedly across machinery and equipment.

Immediate warehouse availability supports:

• scheduled maintenance
• emergency repairs
• machinery overhauls
• preventive maintenance
• replacement of worn sealing elements

For MRO operations, a small O-ring can be a critical component. Maintaining adequate stock helps avoid unnecessary downtime while waiting for replacement seals.

Storage of Bulk NBR O-Rings

Large quantities intended for gradual consumption should be stored under conditions that minimize elastomer ageing.

Protect O-rings from:

• direct sunlight
• UV radiation
• excessive heat
• ozone sources
• aggressive chemicals
• unnecessary stretching or deformation

Correct storage is especially important when a 1000 pcs bulk pack is expected to supply production or maintenance operations over an extended period.

NBR 14x2.5 1000 pcs for B2B Supply

This bulk variant is intended for:

OEM: serial assembly of components and machinery
Production: recurring consumption on manufacturing lines
MRO: machinery repair and maintenance
Maintenance departments: technical spare-part inventory
Resellers: industrial sealing distribution
Warehouses: safety stock for recurring requirements

The 1000 pcs quantity clearly positions this product as an industrial bulk supply option rather than a small-quantity retail package.

Frequently Asked Questions by Engineers

What is the outside diameter of a 14x2.5 mm O-ring?
The nominal outside diameter is approximately 19 mm, calculated from the 14 mm inside diameter plus twice the 2.5 mm cross-section.

What does 70 ShA mean?
70 ShA means the NBR compound has a nominal hardness of 70 Shore A, a widely used hardness for general industrial O-ring applications.

Is NBR 70 ShA suitable for mineral oil?
NBR provides good resistance to many mineral oils. Compatibility should still be verified for the specific fluid, additives and operating temperature.

Can a 14x2.5 O-ring be used in hydraulic systems?
Yes, provided the dimensions, material, groove geometry, pressure and operating medium correspond to the application.

Why choose a 1000 pcs bulk package for OEM production?
A bulk pack supports repetitive assembly, reduces replenishment frequency and allows the same sealing size to be maintained as production inventory.

Is NBR 14x2.5 suitable for pneumatic systems?
NBR is widely used in pneumatic equipment. Final suitability depends on pressure, lubrication, groove design and operating conditions.

How should 1000 NBR O-rings be stored?
Store them in a dry, protected environment away from sunlight, UV radiation, excessive heat, ozone and chemicals that could degrade the elastomer.
