Air line fittings/ DOT

No you won’t have any problems

 

If it's too shiny DOT will look for something else to find.

 

Are you using stratoflex line or synflex. That fitting is not what is normally used for synflex, or is that for the rubber line like going to a brake can?

 

Usually brass is marked if its DOT approved, but I think they are more concerned with the rubber lines, plastic lines, and the fittings adapting them to thread. Your adaptors to the valve should be OK.

I would think you would have to really piss off the officer to get him to find that fitting.

A nice coat of gloss could only help divert their attention.

 

Like said, you’ll be fine, just don’t get caught running around with the officers wife!!!

 

Got you, those fittings are not marked normally, can actually be brass or steel even.

 

Just remember not to mix up 45 vs 37 degree fittings. Steel jic hydraulic fittings are 37. Propane service and i believe air brake are 45. If im not mistaken.
