حلقات O من النيوبرين | 0.103" CS × 0.486" ID | AS568-112 | داش 112 | صلابة 70 (800/عبوة)

These arrived well-packed and the 70 durometer feels just right for the coolant lines I’m rebuilding. I appreciate that the -45°F rating gives me peace of mind for winter storage, and the 800 count means I won’t be reordering any time soon.

I needed a bulk supply for pneumatic fittings, and these 70 durometer neoprene rings have a nice consistent feel and fit snugly without leaking. The chemical resistance is holding up well against the minor oils and dirt in my shop environment.

These sealed perfectly in my hydraulic cylinder, even with the temp dropping to 20°F. The 70 durometer feels firm but pliable enough to seat easily without tearing.
