Technical Specifications, Uses & Benefits of 10x2 NBR 70 O-Ring (100 pcs)

Overview & Search Intent

The O-Ring 10x2 mm NBR 70 (100 pcs) is a standardized rubber sealing ring widely used across many industries. English-speaking buyers often search with terms like “10x2 o-ring NBR 70”, “rubber seal 10x2 mm”, “NBR 70 O-ring set”, “10x2 mm nitrile o-ring 100 pcs”. This description incorporates those keywords naturally to enhance search ranking.

Key Specifications & Material Properties

• Inner Diameter (ID): 10 mm

• Cross-section / Thickness (CS): 2 mm

• Quantity: 100 pieces

• Material: NBR (nitrile butadiene rubber / Buna-N)

• Hardness: 70 Shore A (ShA)

• Color: typically black

• Operating Temperature Range (typical for NBR 70): approx. -30 °C to +125 °C (depending on compounds)

• Resistance: good resistance to mineral oils, greases, hydraulic fluids, fuels, and general industrial oils

• Tolerance / Standard: matches metric O-Ring norms (e.g. DIN / ISO metric sizing)

Vendors reporting such O-rings (10x2 NBR 70) cite their suitability in hydraulic systems, pumps, and fluid sealing environments.

Benefits & Features

1. Excellent oil and grease resistance — NBR 70 performs well in contact with oils and lubricants.

2. Uniform sealing across many applications — thickness 2 mm allows use in grooves, pipes, valves, connectors.

3. Bulk pack convenience (100 pcs) — ideal for maintenance, production, spares.

4. Standardized dimensions — ensures interchangeability across brands and setups.

5. Durable under service conditions — resilient, good compression set resistance.

6. Cost-effective per unit in bulk packaging for industrial users.

Common Applications

• Hydraulic and pneumatic systems

• Pumps, compressors, valves, and fittings

• General machinery and equipment

• Automotive systems (low-pressure seals)

• Fluid handling systems (oil, fuel, water circuits)

• Maintenance, repair, and spare parts for industrial plants

Because this O-ring size is common, it's widely adopted in many OEM and aftermarket uses.

FAQ - Common Questions

Q1: What does “NBR 70 ShA” mean?
A1: NBR refers to the nitrile rubber material (Buna-N), and 70 ShA (Shore A) is the hardness rating — medium firmness suited for many sealing tasks.

Q2: Are these O-rings suitable for oil exposure?
A2: Yes — NBR 70 is well matched to resist mineral oils, greases, hydraulic fluids, making it standard in many fluid sealing applications.

Q3: Can they handle high temperatures?
A3: They can generally operate up to about +125 °C (depending on compound), though prolonged exposure to higher heat reduces lifespan.

Q4: Can I use them in dynamic seals (moving parts)?
A4: Often yes, but depends on speed, pressure, friction and lubrication. For high-motion applications, choose appropriate groove design and ensure lubrication.

Q5: Why buy 100 pcs?
A5: A bulk pack ensures spare seals are available, reduces unit cost, and is ideal for maintenance, service, or production use.
