I have been searching for the hose and fittings for the radiator vent line. The old one came out the top of the radiator and this new radiator has the fitting on the side. I just need to get a straight fitting in place of the 90 degree. The hose looks pretty crappy too so I would like to replace it as well. The problem is I cannot find any P/Ns or references to them in any Foretravel docs. Attached is a cutaway of that section of the radiator where the fitting goes. Also a pic of the fitting and hose. I know the radiator end is 1/4" NPT and it apparently goes to a JIC fitting. From what I can see it is 1/2-20 which is -5. Never even seen one of those before. Any insight would be appreciated. Worst case is a make a new hose with off the shelve fittings.
That's a JIC fitting, real common. Just go to a place that make hoses and they will fix you up.

So the 1/2-20 is the thread pitch which isn't used for sizing. AN fittings go by 32nds of an inch. A -5 would be 5/32. They do make them but not used very often. Only example on the coach I can think of is on the electronic fan controller as a means to prevent swapping lines on the wrong port
The 1/8 NPT and a # 4 on the other.
Thanks all for the info. I am going to just get the AN4 fittings for each end and make the hose. Quick and easy instead of searching all over to make it match what is on it.
