Hannah ★★★★★

Finally got around to replacing all the worn o-rings on my old pneumatic cylinders, and these fit the AS568-111 slot perfectly with no binding. The 70 durometer feels just right for a solid seal without being too stiff.

Hazel J. ★★★★★

The durometer feels spot-on for the pneumatic circuit I rebuilt—seals snug without deforming. I appreciate knowing they’ll handle up to 250°F, which gives me confidence for warmer hydraulic applications. Good value for a bulk pack of 1100.

Zoe P. ★★★★★

These o-rings fit perfectly into a pneumatic valve I was rebuilding, and the 70-durometer hardness feels substantial. The 0.103" cross-section seated nicely, and the package of 1100 gives me plenty of spares.
