Stella U. ★★★★★

I needed a reliable seal for a high-heat application and these o-rings fit the bill perfectly; the package of 125 is generous for the price. They slipped into the groove without deforming, and after a few thermal cycles up near 400°F, there’s no sign of hardening or cracks.

Evelyn ★★★★★

The 90 durometer hardness is noticeably stiffer than the standard 70, which is exactly what I needed for a high-pressure seal. They slid into the groove with a snug, confident fit, and the 1.234" ID measured up perfectly. Solid buy for the price.

Ellie ★★★★★

The temperature range is exactly what I needed for a high-heat application near an engine manifold, and each ring seated perfectly without any distortion. I ordered these for a one-time rebuild job and the pack of 125 will last me through many more projects.
