Customer Reviews (4.2 / 5 · 5 reviews)

Owen ★★★★★

Finally, a red o-ring that's actually easy to spot when it drops on the workbench. The 70 durometer is firm enough to hold a seal but still compresses nicely into the groove, and the -80°F rating gives me confidence for cold storage applications.

Eva ★★★★★

Had an old lab vacuum oven that needed new seals, and these o-rings fit perfectly. The red silicone feels high quality, and the -80°F to +450°F range gives me confidence for heat cycling.

Richard ★★★★☆

Used these to replace worn seals in a hot-water valve at work, and the -80°F to +450°F range gives me peace of mind even though we only run around 200°. The red color makes them easy to spot on the bench, though the 70 durometer feels slightly firmer than the originals—still seals perfectly fine.
