Customer Reviews (4.2 / 5 · 5 reviews)

Hazel R. ★★★★★

The 4.739" inner diameter was spot on for my flange, and the red silicone is easy to spot during assembly. Handled steam exposure up to the 450°F rating without any warping, and the 70 durometer gives a firm but forgiving seal.

Victoria ★★★★★

I needed a replacement for a high-temp seal that kept failing, and these held up perfectly at 400°F without any hardening. The 70 durometer feels just right for my application—not too squishy, not too stiff.

Leo ★★★★☆

The 70 durometer is stiffer than some softer seals I've used before, but it holds tight under high heat cycling. Nice to have a bulk pack of the exact red AS568-048 size for a few different projects.
