Harper ★★★★★

I needed o-rings that could handle high heat for a lab sterilizer, and these hit the mark. The -80°F to +450°F service range gives me peace of mind during autoclave cycles. They fit snugly with no leaks after a week of use.

Robert ★★★★★

The 70 durometer is exactly what I needed for a high-temp vacuum seal — these red silicone rings held up perfectly at over 400°F in my test run. Fit snugly on the first try without any stretching or tearing.

Lily S. ★★★★★

My water filtration housing needed these exact 6.975" rings and the 70 durometer silicone seals nicely without being too hard to install. The red color makes them easy to spot during maintenance checks.
