❓ Frequently Asked Questions (FAQs):
Q1: Why choose Viton rubber over Nitrile?
A1: Viton (FKM) is chosen when:
-
Operating temperatures are above 100°C
-
The seal is exposed to fuels, chemicals, or aggressive fluids
-
Long-term durability is needed under extreme conditions
It outperforms nitrile in heat and chemical resistance.
Q2: What is the purpose of the double lip design?
A2: The double lip construction enhances performance by:
-
Retaining lubricants with the inner lip
-
Blocking contaminants like dirt, water, and dust with the outer lip
This provides extra protection in demanding environments.
