Lucy ★★★★★

I've been using these AS568-153 o-rings for a hydraulic repair project and the -40°F to +250°F temperature range is holding up perfectly. The 70 durometer gives them just the right firmness for a snug seal without being too stiff.

Scarlett ★★★★★

The durometer rating was exactly right for sealing a water filter housing I repaired last weekend. These -153s slid into place nicely and the pack of 250 will last me years.

Carter G. ★★★★★

Used these for a few small pneumatic projects and the 70 durometer feels just right for a snug seal without being too stiff. The pack of 250 gives plenty of spares for future repairs.
