AN fittings size

[MB43]

How do you determine what size AN fittings you need?

I've got a radiator that needs AN fittings on the hoses, but I've got no clue what size they are. See the crappy cell-phone picture below.

Do I measure the OD? The ID? What? Help!

AN sizes are easy. Each size = 1/16th of an inch, so a 6 an is 3/8 ths, 8 an is 1/2 inch, etc.

Measured where? Inside? Outside? At the threads?

 

[ramcharger]

Inside diameter of hose you plan on using.

 

[MB43]

Inside diameter of fitting.

Cool, I'm going to measure it now!

 

[ramcharger]

Measure the ID of the nipple (male end) and add a 1/16th.

I measured it with my caliper, it seems to be .595 of an inch. Does that make any sense?

Hold on on a sec. The girlfriend called and forgot where I left my machinist rule!

Heater hose fitting?

Heater hose fitting?

No, it's for a radiator. See the first post in this thread.

Thanks for the info!

Thats bigger then 10an. Its got to be at least a 14an

 

[MB43]

What?

5/8 ths sounds way small for radiator fittings but thats what it measures at.

My neighbor has a drawer full of fittings, I'm gonna grab some and see what fits. Trial and error is the way to go in this case I guess. ;-)

Thanks for the help!

That looks like a -10 to me and it measures the same as one. I agree with Adam though.....-10 is a little small for a Radiator fitting.

Eyeballing it I'd say a 12 and a 14.

It looks like it is supposed to run two AN10

The top looks bigger to me...But it may be the lighting... Where did that radiator (like what kind of race car?) come from.

 

[MB43]

I don't remember, to tell the truth. I picked it up at a swap meet, or on eBay. It's been sitting in my garage for a couple of years... every race season I have problems with cooling my car down and I keep threatening to put that radiator in. This year I'm gonna do it!

Did ya figure it out yet?

Nope, not yet. I haven't had time to get back to it.

I was thinking about not even using that one, I really need a rad that has the outlet on the driver's side instead of the passenger's side. I got a quote on a a 19x26 unit set up how I'd need it for a good price, I may just buy a new one.

Anybody want a radiator? ;-) I think it's an AFCO, it looks just like this one, except the fittings are on the other side: http://cgi.ebay.com/ebaymotors/AFCO...QQihZ009QQcategoryZ107066QQrdZ1QQcmdZViewItem
