Joseph ★★★★★

I’ve been using these in a high-temp hydraulic application and they’ve held up perfectly at 350°F without any hardening. The 90 durometer gives just the right firmness for a secure seal without being brittle.

Henry ★★★★★

These are exactly the right dimensions for my AS568-331 application, and the 90 durometer hardness makes them feel much more solid than the standard 70s I've used before. The 400°F rating gives me peace of mind for the hot oil system I installed them in.

Ellie ★★★★★

The 90 durometer Viton is noticeably stiffer than the standard 70s I've used, which made seating them in a tight gland much easier without rolling. They've held up fine through a few heat cycles right up to the 400°F spec, and the pack of 30 is a solid value for the price.
