David ★★★★★

These brown Viton o-rings are handling 350°F steam in a compressor test rig without any softening, which the standard Buna ones failed at. The 75 durometer feels noticeably firmer than I expected, a good sign for sealing at high pressure. Just wish they were a little less expensive per pack for this

Christopher H. ★★★★★

The cross-section is exactly 0.21" as listed, and they slid into the groove without any wrestling match. These brown Viton rings handle the heat range I need—up to 400°F—without a hint of softening. A solid 40-pack for the price.

Riley N. ★★★★★

I needed o-rings for a high-temperature steam setup, and these Viton FKM ones handle up to 400°F without any issues. The 75 durometer feels solid, and the 1.099" ID was exactly right for my application.
