Avery ★★★★★

The 90 durometer hardness is exactly what I needed for a high-pressure seal — these rings haven't deformed a bit after a week of constant use. The 2.859" inner diameter fit my groove perfectly, and at 200 per pack, I've got plenty of spares for future repairs.

Benjamin ★★★★★

These 90-durometer o-rings are holding up much better than the standard ones I was using on a hydraulic repair. The 2.859" inner diameter fit the groove perfectly, and they haven't hardened despite running near 200°F.

Timothy ★★★★★

I needed a reliable seal for a high-temp hydraulic line, and these 90-durometer o-rings fit perfectly with a 2.859" inner diameter. They hold up well under the heat, no issues after a week of constant use.
