Sofia B. ★★★★★

Had a coolant leak on a home compressor and these AS568-422 o-rings fit perfectly, sealing right away. The 70 durometer feels firm enough for the job, and the 50-pack gives me plenty of spares for future repairs.

Eva ★★★★★

Slid right into my AS568 port with just a little silicone lube, and the 70 durometer feels solid enough to hold pressure. I've used these on a coolant line running at about 180°F and they haven't hardened or cracked after a week.

Stella X. ★★★★★

The dash 422 sizing was spot on for my application, and the 70 durometer feels exactly right for a firm seal without being brittle. I've had them holding up fine in a hot oil line that stays around 200 degrees, no swelling or hardening after a few weeks. These will be my go-to stock for future repai
