Timothy D. ★★★★★

I needed a bulk supply for a hydraulic repair job and these AS568-911 rings fit perfectly, the 90 durometer holds up well under pressure. No issues with seal integrity so far, even at the higher end of the temperature range.

Ruby ★★★★★

The temperature range on these is exactly what I needed for my outdoor hydraulic setup. They seat well in the groove and the whole pack of 700 came clean, no flash or defects.

Avery B. ★★★★★

The 90 durometer is noticeably stiffer than the standard 70, which made seating these in a tight pneumatic port much easier. I’ve had no leaks since installing them, and the 700-count bag will last me years.
