Customer Reviews (5.0 / 5 · 5 reviews)

Lucy ★★★★★

These seals fit perfectly into my pressure cooker valve assembly. The silicone feels noticeably more flexible than the Buna-N ones I was using before, and at this price for 300, I'll have replacements for years.

Daniel B. ★★★★★

I swapped the old worn-out o-rings on my pressure cooker with these silicone ones and they seal perfectly, no leaks at all. The 70 durometer feels just right—firm but not too stiff.

Riley Q. ★★★★★

These are perfect for a hot water recirculation pump I rebuilt; the 70 durometer silicone is flexible yet holds its seal even at 200°F. The bright red color also makes them easy to spot if one drops during assembly.
