Alexander ★★★★★

The cross-section on these 246 o-rings is exactly 0.139", so they fit snugly in my hydraulic cylinder groove without any play. The 50-durometer material feels pliable enough to seal well, and they were a perfect match for the old ones I removed.

Abigail ★★★★★

Finally getting around to replacing the seals on my old air compressor, and these nitrile o-rings fit the 4.484" bore perfectly. The rubber feels sturdy and not overly stiff, much better than the brittle originals I took off.

Joshua ★★★★★

Needed a fresh set of o-rings for a hydraulic cylinder rebuild, and these 4.484" ID ones fit the bore perfectly. It's reassuring to have the -40°F temperature tolerance since my shop isn't always heated. Definitely got the job done without any leaks.
