FAQs

1. Why choose a 90 durometer Viton® O-Ring?
The higher durometer rating enhances extrusion resistance, ideal for high-pressure hydraulic and SAE fittings where softer compounds may fail.

2. Can Viton® O-Rings withstand exposure to fuels and lubricants?
Yes — Viton® provides superior compatibility with fuels, oils, and lubricants, maintaining flexibility and seal integrity at elevated temperatures.

3. Is this brown O-Ring different from standard black Viton®?
Yes — the brown Viton® compound designates a 90 durometer, high-performance formulation optimized for heat and chemical exposure.
