When I built my horn, I decided to use 1/2" ID Goodyear hose to connect my solenoid to my horn. My horn is so close to my tank, so I mounted the solenoid on the tank and used a 3’ piece of Goodyear hose to connect it. What are the benefits of using air line instead of air hose?
Also, I have another question. What is my limiting factor or “weakest link”? My tank has 1/2" ports. I have a 1/2"male-to-3/8"female adaper in that port, connected to a 3/8"male-to-3/8"male 45 degree elbow connected to a 3/8" solenoid then my 1/2" ID hose connecting it to the horn.
One end of the hose (the end connected to the solenoid) has a 3/8" male barbed hose connector, and the other end of the hose (the end connected to the horn) has a 1/2" male barbed hose connector. The barbed part of both of these connectors (the 1/2" and the 3/8") are the same size, so my assumption is that these barbed hose connectors are the limiting factor of my air system but that the size of fitting (1/2" or 3/8") makes no difference at all. Is this correct?
bottom line is you need volume your pressure comes from the tank… and if you have 1/2 ports down to 3/8 then your pussing 3/8 into the horns even if u go to 1/2 at the horns… it seems like your running 3/8 that short… buy the dot approved line from hornblasters and go with 1/2… you will be more happy…
You missed my point, but that’s ok. Try to picture this…you have a piece of Goodyear 1/2" inside diameter hose. That hose has a 1/2" npt fitting at one end and a 3/8" npt fitting at the other end. On each of those fittings is a barbed hose fitting that fits inside the 1/2" inside diameter hose. The inside diameter of both the 1/2" npt-to-1/2" barbed fitting and the 3/8" npt-to-1/2" barbed fitting are EXACTLY THE SAME. Both are limited by the inside diameter of the 1/2" barbed hose fitting.
Is the inside diameter of a 1/2" barbed hose fitting (which fits into an air hose with an INSIDE DIAMETER of 1/2") really that much smaller than the inside diameter of a compression fitting that fits an air line whose outside diameter is 1/2"?
It is…because simply think about it, if the 1/2OD line fits IN there, the line is 3/8" ID. 1/2" npt can hold a 5/8" barb, and a 3/8" can hold a 1/2" barb. 1/2" ID line, is 1/2" like…the npt sizes don’t have anything really to do with it…
I think that’s what your asking? If its a 1/2" compression fitting then the line is going to be smaller inside it, unlike the barbs, which a 1/2" barb is 1/2 ID
The weak point would be your 3/8" selenoid…1/2 at least, if not a 5/8" one to flow more air:)
I understand that, but the 3/8" npt fittings on the solenoid are much larger than the 1/2" barbed hose connections. Just looking at everything, the smallest point in the system seems to be the 1/2" barbed hose fittings. I am just wondering if the fittings that connect to the 1/2" OD air line are as small as the 1/2" barbed hose fittings. I could always up the hose size to 3/4" if I need to as well.
The 1/2" barbs are made for 1/2" inside diameter line, 1/2 compression fittings are for 1/2"outside diameter line…trust me, I tried fitting 1/2" OD line over a 1/2" barb and it did NOT work. The line is much smaller, about 3/8" ID. Your 3/8" selenoid is the bottleneck…the in and out might be larger then the barbs, but not the selenoid chamber itself.
