Aurora ★★★★★

Had a small hydraulic line leak on my log splitter and these dash 314 rings fit the groove perfectly, sealed right up with no issues. The 70 durometer feels just right for this application, not too hard or too soft.

Nicholas ★★★★★

These 70 durometer o-rings fit perfectly in the standard groove I machined for the AS568-314 size. The black Buna-N feels firm yet pliable, and the pack of 400 gives me plenty of spares for future projects.

Alexander ★★★★★

I had a little trouble seating these at first, but once I got them seated right they sealed perfectly. The 70 durometer feels just right for my hydraulic lines, and the price for a 400-pack is unbeatable.
