The O-ring will seal on the counterbore, which the drawing describes as a spotface. In this low pressure situation I didn't see the need in making the part significantly more expensive and machining the tight tolerance multi-angle bevel that is shown in the above drawing.
In other news, the first shipments will go out today!

Our ORB machining for the same application (engine coolant) was initially done as you have made yours. Ultimately there were issues with it. There's many variables at play that affect how well that oring seals. You are relying on the end user to tighten the fitting to xx oring squish, and that the fitting doesn't rotate (not an issue with yours, is an issue if you use an AN fitting that also get's a hose screwed to the opposite end), and the variable squish of the oring changing with temps/age/coolant contamination. The only thing keeping the oring from expanding and ultimately splitting is it's press between two theoretically parallel surfaces. Coolant is slippery. Aluminum expands when warm. Engine vibrates a lot. Spraying coolant on the track/road is not ideal.
Creating a simple Oring c'bore solves all of this and costs nothing extra. Well maybe adding a 45° chamfer/oring lead to the c'bore with your spot face tool but your edge breaks look nice after the tumbling.

Thanks for the overwhelming interest in these parts. We're working to get another batch in as soon as our machine shop can pop them out. Shooting for 1-2 weeks, but I should have a more concrete eta by the end of the week.
