Intake flare port for heater hardlines

[vacuum 6]

Can someone tell me if this port is a 45 or 37° flare?

I can't directly answer your question but I recently replaced mine with an aluminum piece from Summit P/N SUM- 220047N. The part was described as an -10/1/2" NPT adapter. Fit perfectly. Hope this helps you.
