Avery U. ★★★★★

These 50-durometer o-rings are noticeably softer than the standard 70 durometer, making them much easier to seat in tight grooves without deforming. The 130-pack is a solid value for stocking up.

Leo I. ★★★★★

I needed a tight seal on a hydraulic cylinder repair, and the 50 durometer on these 217 o-rings provided just the right flexibility without crushing. The pack of 130 was overkill for one job, but it's nice having spares for future projects.

Timothy F. ★★★★★

The 50 durometer softness is exactly what I needed for a low-pressure seal where a harder ring would've leaked. These are the right size for the groove, no stretching or rolling when I installed them. Having 130 in the pack means I've got spares for the next few rebuilds.
