I double checked it when I got home and it looks like a 5/8-18 UNF thread adaptor. So much for my 61 year old brain cells. The hieater nipple does look to be slightly tapered so it is probably a NPT piece - but I'm banking on the manifolds being a straight UNF tapping. No luck at Sears but I found a tap and 37/64 drill bit at McMaster-Carr and ordered it. So, with a little luck the JB Weld can stay put away.
