Robert W. ★★★★★

These o-rings fit perfectly on my hydraulic cylinder rebuild and I appreciate that they're rated for the higher temperatures we see in the shop. The 0.724" inner diameter was exactly what I needed and the 300 count should last me through several jobs.

Kevin E. ★★★★★

The 90 durometer hardness is perfect for my hydraulic fittings—no more deformation after installation. This pack of 300 gives me plenty of spares for a long time.

Matthew I. ★★★★★

My air compressor kept losing pressure until I swapped in these 90 durometer rings—much more durable than the standard ones I had before. They fit the .724" bore perfectly and withstand heat in the hydraulic system without deforming.
