Applications & Industrial Use
This O-Ring 5x1 NBR 70 Shore A is a precision rubber seal engineered for demanding industrial sealing applications. Its compact cross-sectional dimensions (5 mm inner diameter x 1 mm thickness) make it ideal in small hydraulic and pneumatic systems, fuel valves, gearboxes, instrumentation, and minor fluid control assemblies. Because it resists many oils, greases, and fuels, it's commonly used in hydraulic systems, fuel lines, automotive components, compressors, and general machinery requiring a reliable oil-resistant seal.
Supplied as a pack of 1000 pieces, it's optimized for production lines, maintenance operations, and bulk procurement, reducing handling costs and supply chain interruptions.
Key Advantages & Technical Features
-
Oil & fuel resistance (NBR): Nitrile rubber (NBR) with 70 Shore A hardness provides excellent compatibility with mineral oils, greases, and many fuel types, making this O-ring a trusted oil-resistant seal.
-
Balanced hardness (70 ShA): Ensures flexibility for sealing under pressure, yet retains structural stability — making the rubber gasket both resilient and durable.
-
Compact 5x1 profile: The minimal cross-section is perfect for tight grooves, narrow sealing gaps, or thin wall housings.
-
Large quantity pack: 1000 units per batch enables cost-effective usage across multiple assemblies or service kits.
-
Versatility in installation: Suitable for static sealing, low-speed rotational interfaces, and light reciprocating motion in industrial sealing setups.
-
Low maintenance & long life: The material’s stability over temperature and exposure to fluids helps prolong service cycles and reduce downtime.

FAQ — Frequently Asked Questions
Q: Is this O-ring suited for both static and dynamic sealing?
A: Yes — primarily for static sealing and light movement. For high-speed rotary or heavy dynamic loads, more specialized seal types should be considered.
Q: Will this O-ring degrade in contact with hydraulic oil?
A: No — NBR 70 is specifically selected for oil resistance, making it compatible with many mineral-based oils, greases, and fuels under typical service conditions.
Q: What is the expected service temperature range?
A: Generally between -30 °C and +120 °C. Exceeding this may reduce elasticity or cause degradation over time.
Q: Can I use this O-ring for fuel or gasoline systems?
A: In many cases yes — for petrol or light hydrocarbon exposure, NBR often performs adequately, provided the environment is within the material’s compatibility limits.
Q: How soon can I receive this product?
A: We stock it in Poland. 24h delivery is available.
