❓Questions & Answers
Q1: What advantages does the double lip design offer?
A: The double lip design provides dual sealing surfaces: one lip retains lubricants while the second lip blocks dirt, dust, and moisture, improving the seal’s lifespan and performance.
Q2: Why is Nitrile Rubber (NBR) used for the sealing lips?
A: NBR is resistant to oils, greases, and many chemicals, maintaining flexibility and sealing properties over a broad temperature range, making it ideal for general-purpose oil seals.
