No problems. Unclear if this is Hartzell OEM or produced by another company.

Wow, what can I say about this O-ring? It has everything you could possibly want! I mean, it is round, soft, fits in a groove, and seals out oil to prevent those nasty leaks! Ingenious! You should buy this today! Im so excited I want to buy more right now, but I think Ill wait until I actually need them again. (Seriously Aircraft Spruce? You really wanted me to review an o-ring?) :-)
