Emma ★★★★★

Exactly the right size for rebuilding a hydraulic cylinder on my log splitter. The 50 durometer is soft enough to seal well without being a pain to seat. This batch of 130 should last me a long time.

Timothy ★★★★★

Swapped out some old harder o-rings with these 50-durometer ones and the seal is much better on my hydraulic fitting. The pack of 130 should last me quite a while for small projects.

Emma D. ★★★★★

The soft 50-durometer compound is perfect for a low-pressure seal I needed—it seats gently without distorting. I've used these in a coolant line sitting right at 240°F and they've held up flawlessly for three weeks so far. The 130-count pack means I've got plenty of spares for the next job.
