Customer Questions & Answers

What advantages does NBR material offer compared with other rubbers for O-rings?

NBR (nitrile) stands out for its good resistance to oils, fuels and weak acids, making it suitable for automotive and industrial applications. It offers better chemical resistance than SBR rubber, and withstands temperatures between -30 °C and 100 °C, although materials such as FKM (Viton) can exceed its thermal and chemical tolerance, especially against aromatic solvents.

Are there any notable limitations when using these O-rings with substances such as acetone, strong acids or fluids above 100°C?

Yes, NBR is not compatible with ketone solvents (such as acetone), strong acids (concentrated sulphuric or nitric acid), or applications above 100°C. Exposing the O-rings to these conditions can cause swelling, degradation or loss of sealing. For such cases, FKM or EPDM is recommended, depending on the substance and required temperature range.

Is any maintenance recommended to optimise the service life of the O-rings in the set?

It is recommended to store the O-rings in their original box, away from UV light, ozone and excessive heat (ideally below 25°C). Before installation, check that the sealing surface is clean and free from sharp edges. Service life can exceed 5 years under ideal storage conditions and non-aggressive use.

Does the set come with a certificate of conformity (RoHS, REACH) or safety compliance documentation?

These types of sets, intended for general use, commonly do not include individual certificates of conformity (such as RoHS or REACH) or regulatory documentation. If the end use requires it, it is advisable to check with the distributor for specific details, as traceability depends on the manufacturer and the particular batch.

What applications is this O-ring set suitable for?

It is suitable for repairs and maintenance in automotive use, hydraulic systems, pneumatic systems and industrial applications that require resistance to acid, petrol and steam.

What sizes are included in the O-ring set?

It includes 419 pieces in 32 metric sizes ranging from 3mm to 50mm outer diameter, with different thicknesses for various applications.

What substances is NBR resistant to?

NBR is resistant to fuels, oils, acids and steam, which helps ensure durability in demanding environments.

Does it come with any storage case?

Yes, the set includes a plastic case that makes storage, organisation and transport of the O-rings easier.

Is it compatible with vehicles and industrial machinery?

Yes, this set is compatible with a wide range of vehicles and machinery that use standard metric O-rings.
