Customer Reviews (4.2 / 5 · 5 reviews)

Evelyn I. ★★★★★

Used one to replace a leaking seal on a hot oil line at work, and the high-temp rating up to 400°F is exactly what I needed. The brown color made it easier to spot against the black metal, too. No issues after a week of constant use.

Henry V. ★★★★★

Had to replace the o-rings on a high-temp line that kept failing with standard rubber, and these Viton ones at 400°F rated are holding up perfectly so far. The 0.21" cross-section seated snugly into the groove without any wrestling. Only wish they came in a bigger pack, but 8 was enough for the job.

Victoria Z. ★★★★☆

These fit perfectly on my old pressure cooker valve I was trying to resurrect. The brown color makes them easy to spot against the metal, and the 75 durometer feels just right for a snug seal. Only giving four stars because the package of eight is more than I needed for a single repair.
