Madison ★★★★★

Had a vacuum leak in a fitting that sees some serious heat, and these Viton rings sealed it right up. The 0.921" inner diameter was a perfect match, and handling them at 90 durometer feels solid without being brittle. Worth grabbing the 150-pack since you'll always find a use for them.

John H. ★★★★★

The 90 durometer hardness makes these easy to install without deforming, and the 400°F rating gives me confidence for my hot oil applications. Ordered the 150 pack and every single ring has been perfectly uniform so far.

Jason R. ★★★★★

Finally a Viton O-ring that actually handles the heat in my engine bay without getting brittle. The 90 durometer feels substantial and seals my oil fill cap tightly.
