Lucy V. ★★★★★

I needed a high-temp seal for a steam valve at work, and these Viton FKM o-rings handled the 200°F service range flawlessly. The 200-count pack is great value for the price.

Amelia ★★★★★

The 75 durometer hardness gives these o-rings a nice, solid feel that seals perfectly in my automotive coolant system. I've tested them up to 350°F with zero leaks, and the brown color makes them easy to spot during installation.

Samuel R. ★★★★★

The high-temperature rating was exactly what I needed for a compressor rebuild, and they sealed without any leaks on the first try. The 75 durometer feels sturdier than the standard ones I've used before.
