Thomas ★★★★★

The temperature range sealed the deal for me—my pump sees 200°F regularly and these haven’t hardened or cracked after a month of daily use. The 70 durometer feel is exactly what I expected, and for a bag of 1100, I’m set for years.

Timothy G. ★★★★★

Used a few of these on a coolant line repair at work and they seated perfectly, no leaks even at 150°F. For the price per pack, it's nice having extras on hand for future jobs.

James ★★★★★

These o-rings measured exactly to spec when I checked them with my calipers, and the 70 durometer feels appropriately firm for sealing. Having a full pack of 1100 on hand means I won't be scrambling mid-project again. They seated nicely into my hydraulic fittings without any deformation.
