FAQ - Frequently Asked Questions

Q: What does 90 ShA mean?
A: It’s the hardness rating on the Shore A scale. 90 indicates firm rubber, resistant to deformation under load.

Q: Why choose NBR for O-rings?
A: NBR is highly resistant to oils, fuels, greases, and hydraulic fluids, making it the most common choice for industrial sealing applications.

Q: What is the operating temperature range?
A: Typically from -30 °C to +100 °C.

Q: Why buy in packs of 100?
A: It ensures availability for frequent use in service, repair, and manufacturing, reducing the need for repeated orders.

Q: Can these O-rings handle high pressure?
A: Yes, within their dimensional limits. For extreme pressures, back-up rings may be recommended.
