Plans are:
K3LA
1/2in. air line and valve.
dual Viair 480’s
8.5 gallon tank
I plan on putting all of this where the spare tire was. I painted them this week. i have to get a oil leak and water leak fixed first then they will go on the truck when I get the funds for the rest of the equipment.
Here are a few pics of them after I painted them. I used grey self etching primer then a few coats of flat black paint. Not show quality, but hey they are going under the truck, so i wasn’t really worried about it lol
Thanks man. It’ll take a while bc I got save up money and get the truck fixed. Lol I might post some vids up of the sound system I had in it. Doubt any of you would be interested lol but I thought the paint turned out well beings it will be hidden anyways. Lol
Plan on running 1/2 hose and valve unless someone can convince me 5/8 or 3/4 would be better? It would be restriced at the tank and horn to 1/2. But who knows? Going with a parker valve or smc valve. Plan on running a single pressure switch with the built in relays for 2 compressors. Figured less hassle and wiring, unless someone thinks the seperate relays are better and less prone to trouble. This will definately be done right the first time.
Bigger the line the better… I went 5/8" OD as it is a 1/2’ ID … A 1/2" OD is only 3/8" ID, so that is restricting it… I had 1/2" running mine at first and it was a waste of time and $. I had to rebuy new fittings and hose to upgrade the upgrade… You wont regret it and to me its not overkill… Its what these horns crave and deserve!
but NPT is measured in ID so i need 1/2 NPT fittings and 5/8 line. 3/4 valve or 1/2? also i heard compression fittings were the way to go, but cant seem to find them thst big. anyone have a link i can look at?
Yes NPT is measures ID… Thatg is why if you connect a 1/2" npt valve with 1/2" airline, you have a bottle neck effect because the airline is 3/8" ID… A lot of guys have no problems with this setup tho and run it … I had an issue with it and it sounded way to restricted to me.
1/2" valve will be perfect match if you fun 5/8" line since the ID is same…
My first couple setups i had nothing but problems with compression fittings. I bought a lot of them and had them perfect/ no air leaks… But then with the weather change, (temp change) there were times i’d loose half a tank of air overnight… Finally i got tired of it and switched over to PTC fittings and can go days now with only loosing 5-10 psi or so… But that little bit is caused to outside temps… 0 degrees at night , 45 during day…
As to where to buy these fittings that big… HB does not have 5/8" PTC so i got them along with the 5/8" airline from airridefittings.com
So would I gain anything going to 3/4 and 7/8 lines and fittings? Lol
I think I will do the ptc fittings then bc temperature varies from 105-in the teens. Lol I’m gonna look at those fittings when I get home and check them out.
Also, do the compressors come with leads pre wired? What size wire should ii use for them and the pressure switches?
that k3 looks good. You will be fine with either 1/2 or 5/8 i have 5/8id and 10 gallon tank and it guzzles the tank in less than 7sec and already starving my k5hla of air. The only way a 3/4" or 7/8’ line will pay off is if you have the air volume for it.
Not cast iron. Not the copper pipe chart (modern copper is tubing).
We’re talking about standard ANSI pipe.
There might be generalizations about pipe for common sizes, but the absolute fact is the pipe is by the OD + wall thickness (schedule)
1/2" sch 5 is .840" od x .710" id
1/2" sch 10 is .840" od x .674" id
1/2" sch 40 is .840" od x .622" id
1/2" sch 80 is .840" od x .546" id
1/2"sch 160 gets smaller etc…
^^^none of which measure 1/2" ID. Schedule 40 is the most common and it’s ID is actually closer to 5/8".

ANSI pipe. There are hundreds of charts if you google it. Here’s one:

Take the spaces out of the link - it wouldn’t let me post it.
lol yeah dont have that kind or space nor compressors lol
thanks man. and i plan on running 1/2 ID all the way, hose and fittings. lol
i imagine the k5 takes a little more air than the k3?
also, took apart my horns when i painted them, noticed when i took the diaphrams off, the piece that is held in by allen heads. It was cracked. what exactly does that piece do and where can i find another one or can i machine one?
i thought the measure of the fittings, say they were 1/2 fittings, they would be 1/2 ID and like 5/8 OD?
is that not like PVC pipe? never knew brass fittings or airline could be schedule 40?
Littlefield when you order your fittings dont tell them you want 1/2 fittings for 1/2" airline cause that’s what you will receive when you are really meaning 5/8" airline. Its a good way to get a rep confused about what your wanting.
The steel diffuser ring is meant to equally distribute the air around the nozzle. Let me look around I might have one, if not microprecision should carry them.
Littlefield:
The part in the horn is an air diffuser. Could you post a pic of it? If it’s not too bad, maybe it wouldn’t matter.
Yes PVC pipe is measured the same way.
Do you mean flexible airline? That is either hose measured by the ID or tubing measured by the OD. Sounds like you’re wanting 5/8" tubing like silvy.
Pipe’s wall thickness is it’s schedule. Fittings do not have a schedule. They’re given a pressure rating. To determine the size of a fitting measure the diameter of the threads and compare to a chart. I know McMaster Carr has one.
EDIT: I’m talking about purely pipe fittings. PTC fittings a different animal.
i can take a pic tomorrow sometimes…its not a huge crack, yet its not a hairline crack either. it is cracked all the across though. i tried taking it off and couldnt budge the screws, so i was kinda scared to take it off without getting the correct bit. i was using a attachment that went to the end of a screwdriver.
i have the tools to machine one with a lay. i would appreciate it if you could find the part. pm me and let me know how much.
i am talking about NPT fittings, which goes in the tank and horns correct?
see i thought 1/2 NPT fittings would have a 1/2 ID and 5/8 OD (give or take)
also, i was wondering. the air has to travel further to get to the two outer bells than it does in the middle. is this because the middle takes more air to “open up” than the outer ones? just really never understood how that worked. lol
and whats the difference between these two bells besides the tone? which would sound better? sorry for all the questions guys. gotta start somewhere i guess. lol
