Hannah X. ★★★★★

These red o-rings fit perfectly on my large water pump housing and the 70 durometer silicone feels pliable yet durable enough to handle constant hot water exposure. The -80°F to +450°F service range gives me confidence they'll hold up during both winter shutdowns and summer operations.

Lucy ★★★★★

The 0.21" cross-section was exactly what I needed to replace a worn seal on my industrial mixer. Even after a weekend of high-temp use at nearly 400°F, the red silicone hasn't hardened or cracked at all.

Daniel B. ★★★★★

Used these to seal a large pressure vessel in my lab, and the 70 durometer silicone held up perfectly under high heat. The bright red color also made them easy to spot during installation.
