Timothy Y. ★★★★★

The -40°F to +250°F range is exactly what I needed for my outdoor hydraulic rig, and these 70 durometer rings have held up through a brutal month of freezing mornings. Fit the groove perfectly on the first try, no wrestling or trimming. Solid pack for the price.

Sophia ★★★★★

Ordered a pack of the AS568-423s for a small hydraulic repair and they fit perfectly out of the bag, no guessing needed. The -40°F to 250°F range covers everything I’m working with, and the 70 durometer feels just right for a snug seal without being mushy. Forty in the package means I’ve got spares

Claire ★★★★★

The 70 durometer hardness made these easy to press into the grooves on my pneumatic manifold, and they feel like they'll hold up well against the hydraulic oil I'm using. Packet of 40 is just the right amount for a few spare sets.
