James ★★★★★

Finally got these for a high-temp sanitary line repair, and the 80 durometer held up perfectly under 280°F steam cycling. The 6.975" ID fit snug without any stretching issues.

Timothy ★★★★★

These o-rings fit perfectly on my hydraulic cylinder and the HNBR material gives me confidence in high-heat applications. The 0.21" cross-section is exactly as specified and feels durable enough for long-term use.

Sophia ★★★★☆

These handled the high-temp grease in my pump shaft without any softening, which was my main worry. The 0.21" cross-section fit perfectly into the recessed groove. Great value for a six-pack of this size.
