Charlotte ★★★★★

The 90 durometer feels a bit stiffer than the softer ones I've used before, which is exactly what I needed for a high-pressure hydraulic fitting. These o-rings fit perfectly on my pump flange, and the 250-pack should last me through several jobs.

Sofia ★★★★☆

The 2.359" inner diameter fit perfectly on my hydraulic cylinder, and the 90 durometer material seals well under pressure. Only took off one star because the package of 250 is a lot more than I needed for a small repair job.

The 90 durometer is noticeably stiffer than what I usually grab, which works fine for my high-temp application since it won't deform as easily. Got the full box of 250 and the sizing is dead-on for my groove. Only wish the packaging was a bit sturdier for long-term storage, but the rings themselves
