Hannah ★★★★★

The high temp range on these is exactly what I needed for my hydraulic cylinder rebuild - they slipped on easily and held a seal right away. The brown color actually makes them easier to spot against the black housing too.

Abigail F. ★★★★★

Finally found a Viton o-ring that handles the heat on my autoclave door seals without cracking. The 75 durometer has just the right firmness for a snug fit, and the brown color makes them easy to spot during inspection.

Lily ★★★★★

Installed these on a hydraulic fitting that sees constant heat cycles, and the Viton material is holding up perfectly at 400°F without any softening. The 4.734-inch ID was spot on for my application.
