We have an '02 U320. Hubby has repaired a couple of small air leaks under the rig and behind the step. There is air coming from a nut we can't get a good picture of. But, it looks like it's coming from a screened hole like the one in this picture. Can anyone tell me what this is and what, if anything, I can do to stop the air? Thanks for the help.
That is the Norgren valve do a search on the forum for information.
The valve is shot so you need a new valve and they don't make that
valve any more they have an upgraded one that works.
See Fold Down Step Norgren Valve (https://www.foreforums.com/index.php?topic=41968.0)
A functionally similar valve is 1/4" NPT 5 Way 2 Position Pneumatic Electric Solenoid Valve DC 12 V:... (https://www.amazon.com/Position-Pneumatic-Electric-Solenoid-Valve/dp/B00VU1BVDI/ref=sr_1_30?ie=UTF8&tag=foreforums-20&linkCode=as2&camp=1789&creative=390957)
I think that is an exhaust port on the valve. Could it be the ram leaking past the seals to the exhaust port ?

It is the exhaust port and if you are going to get new ones I would go with
the ones Roger suggested as they are way cheaper than Norgren valve about
one tenth the price. I would have gone that way if I had know about them when
I did my valves.
Thank you all so much! Your experience and guidance is greatly appreciated!
