3/8 Air Hose With 3/8 Fittings

plazaman

For my spraying project, it is recommended that i get 3/8 hose with 3/8 fittings on the ends. Most of the hoses i seen have 1/4 connects at the ends. Even my 3/8 hoses have 1/4 on the end. So instead of buying a hose with 3/8 ends for almost $40, can i just cut my current hose and install new 3/8s fittings or am i being to cheap?

So you are saying that the piece crimped on to the end of your hose that the fitting threads on to is 1/4"? I don't see why you couldn't- new barbed ends are pretty cheap, even for the good ones with the compression fitting kind of thing. I'd doubt that you'd want a 3/8 hose with those restrictions anyways, so you might as well put it to use.

yes, the 3/8s hose was 1/4" NPT ends, i guess its standard.



I would have to cut this one out since its crimped on. How would i install the new ones? I dont have anything that can crimp.

Plazaman, we used to cut off the fitting and replace it with a 3/8 NPT barbed fitting and secure it with a worm drive clamp sized for the hose. Worm drive is what we called them, they are the kind you used to see on radiator hoses that tightened with a screwdriver. We only use poly now the rubber ones haven't been out of the trailer in over 2 years.

The 1/4" NPT fittings are not the bottleneck. It's the 1/4" quick connects that are the bottleneck. Upgrade to 3/8" quick connect fittings and you'll see an improvement. The 3/8" quick connect ID is the same ID as the 1/4" NPT threaded end.

You can use a hose clamp, and they do work, but even better, you can buy barbed fittings with a compression clamp- there is a compression nut that goes on the hose first, then the barbed fitting slides in, and the nut is threaded on to the back of the fitting, and tightens down on the hose. It doesn't create another snag point, is less likely to loosen, and looks original. It probably costs less as well, once you consider the cost of the hose clamps.

here is an example of what I'm talking about. You can probably find it locally.
