Im looking for a fitting for my pressure switch, its a viair 165-200 psi, their website says its npt but it doesn't screw on anymore than one or two threads into a 1/8 to 1/2" npt fitting, anyone else have that problem or know where I can get that fitting from? Ive looked everywhere amd its one of the last things holding me up

Every pressure switch I have ever used is 1/8th npt, except the square D's.

Hit up the local Home Depot. Bring the pressure switch and they will find out what threads u have. You sure the threads aren't dirty? I've only seen 1/8 also

and thats how far it screws in before it starts to bind, I went to homedepot and tried everything

i think its a pipe thread instead of npt but im not 100%

That looks like the same switch I'm running and it's 1/8 npt. Maybe the threads need to be cleaned out.

Its a pipe thread... Ive the same one. I went to a ACE Hardware and they had a galvanized reducer that fit pretty good. Try a plumbing store or a hardware store.

My one before this one screwed right into a 1/8 npt. Same Viair pressure switch just different psi on/off and i bout striped the threads trien to make it go in...lol

thanks, i figured it was pipe thread but home depot didnt have anything that would work, so im gonna try ace or another local hardware place when i get some time, i have another question what are you guys using for brake lines up front? im gonna be running the mmw arms and the uppers dont have a spot to attach the brake line like the stock ones
