AN block plug

I have a World alum. block. I need one of the plugs that screw into the side of the block.anyone know where to get one?its not actually an AN fitting,its a nps frost plug.i can get 4 from Bill Mitchell but I only need one.

NPS = straight threads with the same TPI for the size as the NPT tapered threads.

McMaster-Carr?

Maybe try KB. They may have some on hand. If not they could tell you where to look.

Seems simple to me to get them from Bill Mitchell. I've just spent the last 6 minutes looking (for me that's a lifetime of looking online) and while they are out there, they're really not easy to find. Also they look like plumbing parts, not racecar parts.

How does the plug seal? NPS threads need some sort of seal. One type I found has a hex head with an o-ring under it. Also not cheap at several dollars each.

they seal with a o-ring.i only need one .I havnt heard back from Mitchell.the bummer is,i have one I just cant find it and I know as soon as I order one mine will appear in plain sight right before my nose.if I don't hear back from Mitchell I,ll give KB a call.

I found some online but they didn't have the size I need.the Mitchell web site says they are 1.000 x 11.5 nps.

I FOUND IT!!!!. thanks for the input

I thought that fitting was a -12 ORB (O-ring boss). If it is, that is fairly common. Jeg's, Summit etc.

-12 way to small.
