I think I found the fitting. I'll give them a call tomorrow. Thanks a bunch.
Vegas, the B&M cooler is 1/2" NPT. I was just uncertain if the fittings I had fit because I was only able to engage 3 threads by hand. Seems that is sufficient and with a wrench and thread lube it will engage more.
Thanks for the help guys.
