Air Hose for spray gun

#21
not a fan of Flexzilla because they have very thin walled aluminum fittings on the end and even using the right wrench its going to strip getting the coupler on the first time. The hi flow couplers I have bought are blowing out o rings constantly and have to keep getting changed, its down to needing vise grips to hold onto the hose. Nice flexy hoses, just not a fan of the ends.

As far as the gotta have CFM, I get it, but if you increase the size of your air hose, you are going to require more CFM to get the pressure up. I am sure its not going from 1/4-1/2. but you gotta have the compressor that can do it and you might just hear the compressor running more. I dont know if he has a 2.5 hp pancake tank compressor or a 50 horse screw. If you do not have the CFM, you will not keep that 30PSI consistent at the gun. When you lose the CFM, that pressure is going to drop.
If you don't have a compressor capable of producing the proper CFM to handle your equipment - you need a better compressor. PSI does not equate to CFM in any equation.

i love the flexzilla hoses. i have 2 that are atleast 10 years old now. its the only ones that last except the one i made out of aeroquip line lol. i do know i am not a fan of theose flaxzilla couplers though. as stated they are all aluminum. those woulnt hold up a week around here. i just switch mine to all steel couplers. i get about 2 years of daily use out of a steel end.
Just to be clear, I don't have the Flexzilla hi-flow fittings either just the hose. It is a great hose so I assumed the fittings would be good as well. Sorry for posting an assumption - lesson learned.

I have Prevost couplers that are over 10 years old with daily use. Replaced 2 in the last 15+ years because of getting run over multiple times and finally got hard to connect, but never leaked. Far superior in every way to any Milton coupler, in my experience with both. Connect easy, release easy, never leak, won't scratch as easy, and release with very little "kickback" of the hose or tool. Tried the Milton V style couplers and plugs in the paint shop and some lasted less than an hour using a DA before they didn't want to release. Junk.

I switched over to Milton V's about 5 years ago, and have noticed what everyone here is saying....they don't last long before they start to leak and worst of all become hard to connect and disconnect. When new, they work slick, but they are aluminum, and the more aggressive tools beat the snot out of them. I still have a 20 pack left, and am waiting till I go through them all, before I switch again. I'll try the Prevost everyone here recommends next time.

I know Prevost has the True-Flate couplers, and I know the Milton M style plugs went into the standard Prevost couplers, but I'm not sure if the Milton V style plugs are compatible with the Prevost high flow couplers.
I checked and I do have the Milton V style Hi-Flo. Maybe I'll contact Provost and ask if it will work but if I have to change all the plugs (about a dozen) thats what I'll do.

A lot of people use cheater valves to set the air pressure at the gun. There is no way the correct amount of CFM can go thru those. Am I missing something here?

Thats usually how it goes around here, if you dont have a 1500.00 paint gun, you should not be expecting results.

Bigger hose takes more CFM to continue to deliver the pressure is the simple comment I made. Having it there, able to be used means you gotta get enough there in the first place.

All of my paint guns don't add up to that much.
Didn't mean to offend you however I have tried the undersized compressor route thinking as long as I had the PSI to the gun everything was okay. The truth is that it isn't okay.
Once I broke down and bought a decent compressor most of my problems disappeared. Even the cheap Astro Pneumatic guns sprayed better. The DA that wouldn't run more that two minutes without slowing down and losing power now will run continuously.

I wasn't going to comment but I can't help myself. :mad:This isn't the first time you have made snarky, insulting comments about other members here and I don't understand why. '68 was merely stating a fact. Some things are true whether you want to believe it or not.

When I say that you need this or that, it's because I've made the mistakes and done things the wrong way and I'm trying to help others not make the same mistakes. Trying to help make their path to learning a little easier. Myself and others on here try to share our insight from doing this as our vocation and trying to help folks do things the right way. Not the most half assed way you can get away with. Is that how you are with your profession? Or do you know that things need to be done in such a way as to achieve the desired results? I mean really....:mad:

You feel the need to argue about certain things, techniques etc, when it's clear that you do not do this for a living. Your first post in this thread shows you don't really have a clue. Is your ego so large that you just have to give your opinion whether it's correct or not, or do you just enjoy muddying the waters so that folks who ask a question don't really know what the answer is?:mad:

Only reason I'm responding like this is because the attitude you had in the above post. I'd prefer we could all get along and be nice to each other.

if you use a cheater valve you deserve the results you get .
yep I learned this lesson last year. I did not realize the “regulator” that came with the flg4 gun I had was indeed a cheater valve. I switched over to a motor guard rg4049.

What about a cheaper regulator at the compressor. Can it restrict the cfm as well or are the bigger regulators not as much of an issue?
