what is used for air horns? could i use something like the line for the boost gauge?

 

[Old_Sparky]

Boost will vary. You need 100 psi constant for air horns.

 

[chrisw91]

so, is it no good for an air horn?

 

[rigcrawler]

the line for a boost gauge is too small, you need a minimum of 3/8 to 1/2" synflex, which is the best airline tubing. you can get it at any truck parts store.

 

[chrisw91]

alright, thank you

i got air brake hose for mine 1/2 in

 

[chrisw91]

where do you have it mounted? i want to put it up in the headliner, so i need to use as small as possible

 

[rigcrawler]

i have my train horn mounted on the passenger side frame under the rear passenger door with air tank and compressor going there also, and if you do i find that if you have it facing backwards and downwards a little works to keep rocks and water out of the horn itself, if you want to go trucker style then all means go for it

 

[chrisw91]

i was planning on putting the horn under the truck, but i was talking about putting the valve on my ceiling. where do you have yours?

 

[rigcrawler]

my valve is electric and its also mounted under the truck i just got a button that operates it, i don't feel like having air lines running into the truck because of of all the extra work for something that can easily be done by wire now adays

 

[chrisw91]

oh, so that is a pretty easy way? how expensive? that was my whole issue was running the air line in the cab. but i can do do it electric i might just do that. did you buy the stuff separate? or did it come in a kit? cause im pieceing my own together

 

[rigcrawler]

i did all mine seperately, the train horn, the air tank, and the valve i bought seperate
best place to go is a big rig truck parts store for the electric air valve, that way everything can stay on the frame and the only items inside are a toggle switch for the compressor and a push button for the horn

 

[CajunCowboyCummins]

well i have a true train horn manual valve in mine it is kinda custom install .... i didnt want electric cause i nmy opinion maniual sounds better .... and besides i can give it a true train effect by restricting the air some with the valve or full blast ya know ........

left toggle is for ligths and right one is compressor

 

[rigcrawler]

i see you got synflex there, and nothing wrong with the manual valve, i realized that and thats why i got a stepper valve i didn't mention it and i should of, so it acts the same as yours does there just electric, and still runs a button, hold the button the valve opens take finger off button valve shuts fast.

 

[chrisw91]

this is awsome, thanks for the help. but one last thing, what is a good trucker website? i dont have any big rig places around where i live. what about ebay? what should i type in for the search. and again, thanks for putting up with me!

 

[chrisw91]

would this one here work?
1/4" Chrome ELECTRIC SOLENOID VALVE For Train Air Horn:eBay Motors (item 200334372910 end time May-21-09 14:44:44 PDT)

 

[rigcrawler]

yes that one will work for the full blast air horn, there will be no stepping however, just a direct on/off.

and i'm searching for places for you to go to get the proper stuff to complete the project that you got before you.

 

[chrisw91]

will i still need to run 3/8" hose? if so just adapt it to the 1/4" valve ehh?
