Brian ★★★★★

Finally got the dash 168 size right and these fit snugly without any wrestling. Handled a hot water line up to around 200°F without any leaks, so that -40 to +250 range is reassuring. A hundred in the bag means I’ve got spares for the next few rebuilds.

Robert B. ★★★★★

The 70 durometer feels just right for sealing those moderate-pressure connections I've been working on. These AS568-168 o-rings fit perfectly on my standard fittings and came well-packed for the price.

John T. ★★★★★

The 70 durometer feels just right for my hydraulic lines—firm enough to seal without being a struggle to install. Used a few on a coolant system that cycles near 200°F and they haven't leaked a drop yet.
