FAQ - Frequently Asked Questions

Q1: What are the main uses of the 39.34x2.62 mm NBR 70 ShA O-Ring?
The O-Ring is commonly used for static or face sealing in hydraulic and pneumatic systems, sealing housings, valves and pumps where a reliable rubber seal is required. It is ideal for maintenance and industrial customers seeking high-volume supply of a specific size.

Q2: Is the NBR material suitable for contact with oil and fuel?
Yes. NBR is a go-to elastomer for applications involving mineral oils, fuels and hydraulic fluids. The 70 ShA hardness offers a good balance of flexibility and resistance to deformation under load.

Q3: Can this O-Ring be used in high temperature environments?
While NBR performs well in moderate temperature ranges, it is generally effective up to around +100 °C depending on fluid and pressure conditions. For higher temperatures or more challenging chemicals, alternative materials may be required.

Q4: Why buy in a pack of 100 for industrial procurement?
Buying this size in a pack of 100 simplifies inventory management, reduces unit cost, supports planned maintenance and ensures ready-to-use stock for rapid OEM or MRO deployment.

Q5: How important is the precise sizing (39.34x2.62 mm) in industrial sealing?
Correct sizing of an O-Ring is critical to ensure the sealing gland performs properly—an incorrect ID or CS can lead to reduced compression, leakage, seal failure or shortened lifespan. Metric size charts and standards guide proper selection.
