Penelope M. ★★★★★

The 1.984" inner diameter fits perfectly on my hydraulic cylinder, and the package of 250 gives me plenty of spares for future jobs. I appreciate the -40°F rating since I work in an unheated shop during winter.

Sophia E. ★★★★★

The 90 durometer is noticeably stiffer than the standard 70 — exactly what I needed for a high-pressure application. Fit perfectly on the first try with no leaks.

Benjamin Z. ★★★★★

Ordered these for a hydraulic cylinder rebuild and the 90 durometer held up perfectly under high pressure. The 1.984" ID fit snug with zero leaks on the first test run.
