Hit up your local plumbing supply house. Just tell the what you need. Install it at the high point, with a valve underneath it. Id say even a 1” unit would be fine. You only need it to get system set up. Once you’ve bled the air, you shouldn’t need it again until you work on the system. At least, thats our experience. We keep valve closed for safety sake. Just use it when we open the piping or drain for any reason.

Nothing should air lock in this type of system in 99.99% of cases, and its about that simple.
If you still feel the need to use them, you need to get the industrial type that the relief can be piped back into your return header, for every instance.
This is another additional point of failure.
They are only indicated in closed loop " Pressurized Return " systems.

At any high points in the glycol supply side, I install a 4" high stub facing up. Drill and tap a 1/8" NPT hole in the end cap and install a simple, ball-style bleeder valve. As others have mentioned, you'll rarely need to use the valves, and the stub works as a trap for any stray air.Timm Turrentine
