Customer Reviews (4.6 / 5 · 5 reviews)

Emily ★★★★★

These red silicone rings handled my autoclave cycle perfectly without any softening. The 70 durometer is just right for a firm but flexible seal, and the price for a 22-pack is fair.

Julian E. ★★★★★

These red silicone rings are perfect for my high-temp brewing setup; the 70 durometer feels firm yet flexible enough to seat easily. The FDA compliance gives me peace of mind since they contact my mash tun.

Nicholas Q. ★★★★★

Finally found a 5.484" inner diameter o-ring that actually fits my pressure canner's lid groove without stretching too much. The 70 durometer feels firm but still pliable enough to seat properly, and the red color makes it easy to spot during cleaning.
