I had to trim the bottom a bit for it to fit (the roto fittings are tapered on the bottom outside).

I'm pretty sure it's 3/4" npt. I got that fitting at Lowes a long while back, but I took the factory roto fitting with me and matched them up. Might be flare but either way they can be had.

I just saw today that Kilby is going under. Probably why he won't return my calls. Guess I better get on those fittings and filter! Shame to because nobody does the york thing like them.
