Customer Reviews (4.8 / 5 · 5 reviews)

Brian ★★★★★

The 70 durometer feels just right for my application, and the bright red color makes them easy to spot against dark metal parts. I used these to seal a hot fluid line, and they performed perfectly up to 400°F without any degradation.

Penelope ★★★★★

These fit perfectly on my pressure cooker valve stem; the 70-durometer silicone is stiff enough to hold a good seal even at high heat. Glad I went with the FDA-compliant material for this food-contact application.

Steven ★★★★★

I've been hunting for o-rings that can handle high heat for a hot-water setup, and these silicone ones are rated up to 450°F which is exactly what I needed. The 0.609" inner diameter fits perfectly on my fittings, and they've held up without any swelling after a week of use.
