Jacob S. ★★★★★

I bought these for a high-temp food processing application, and having a metal-detectable O-ring that handles up to 450°F gives me real peace of mind. The 70 durometer silicone feels firm enough for a solid seal but still pliable for installation.

Ruby ★★★★★

I needed something to seal a custom fluid setup where standard rubber would melt, and these silicone rings handled the 200°F sustained test with zero issues. The 70 durometer gave a firm but forgiving seal against the aluminum housing. Worth the extra cost for the temperature range alone.

John ★★★★★

Used these in a high-temp industrial application and they held up perfectly at 400°F without any degradation. The metal-detectable feature gives me peace of mind for food safety compliance. Exactly what I needed for the price.
