FAQ - Frequently Asked Questions

Q: What does “90 ShA” mean?
A: It refers to the material hardness on the Shore A scale. A value of 90 means the rubber is quite firm, maintaining seal integrity under high pressure.

Q: Why use NBR for O-rings?
A: NBR (nitrile rubber) offers good resistance to oils, greases, fuels, and many hydraulic fluids, making it a go-to material for sealing in machinery and fluid systems.

Q: Is 100 pieces a common packing size?
A: For B2B and maintenance environments, 100 pcs offers great value—enough for multiple service needs without frequent reorders.

Q: What temperature range can this O-ring withstand?
A: Generally between -30 °C and +100 °C. The exact limits depend on the NBR compound quality and operating conditions.

Q: Can this O-ring resist chemicals and fuels?
A: Yes — NBR is compatible with many oils, greases, fuels, and hydraulic media. However, avoid strong acids, ketones, ozone, and ultraviolet exposure.
