FAQs

1. Why choose 90 durometer Viton® over 70 durometer?
90 Duro Viton® provides higher extrusion and pressure resistance — perfect for SAE Boss and hydraulic systems operating at high pressure.

2. Is Viton® compatible with Skydrol hydraulic fluid?
Only limited compatibility; for full Skydrol resistance use EPDM or specific perfluoroelastomer compounds like Simriz®.

3. Can Viton® O-Rings be used in fuel systems?
Yes. They excel in diesel, aviation, and gasoline applications where standard nitrile O-Rings would fail.
