    I am always trying to improve my workshop so I have been looking at the new high flow air fittings but was a little disappointed about getting special ones of the internet and most were cheap aluminum and expensive. Then I saw a nice video of the new 3/8” Harbor Freight ones that just came out that are stronger and cheaper.
    Bingo, I got some to try
    The are higher flow, very strong and cheap and easy to get! LOL
    HF 3/8” VS Milton high flow - the purple ones.

    Do you have any high flow air couplers?
    Are they worth it?

    Ah they would probably make quite a difference at that pressure. What do you use 25psi for?

    I have a blasting cabinet and with the old DeWalt 5 psi it did not seem to be enough and the 25 psi is much better but the High Flow couplers should make it a lot better?

    yes I use hi flow fittings, I don't think they are a gimmick.
    My impact has good torque with those fittings. My undercoat gun likes it too.
    I buy the brass milton ones, and as luck would have it. I just picked up a box and I'll share the deal/ link
    because it's too good to miss. yes they are 1/4" but I think that is the way to go.

    I always wondered about them but 155psi made my tools work pretty good for the 15 years i did it. Never bothered with more than the shop provided.

    I got a nice new Harbor Freight Earthquake XT impact and was not impressed with the torque.

    So I am anxious to try this impact now with the High Flow! :)
    My Harbor Freight 3/8” automotive high flows are
    https://www.harborfreight.com/38-in-automotive-quick-coupler-and-plug-set-4-piece-63545.html
    only compatible with Milton H high flows!
    What is the difference between Milton H & V ??

    H = 67 scfm
    V = 74 scfm
    probably won't notice any difference between those 2 I'd guess.
    I went with aircat for my impact.

    I doubt most homeowner-type tools will show a difference. If more air was needed at 25 psi I’d turn the pressure up. These high flow couplers are made for things that draw air…industrial air grinders, 3/4”+ drive air impact tools, things like that

    Correction, I meant 5 CFM and now I am working with 25 CFM @ 90 PSI of course! LOL

    80 gallons but the High Flow couplers suck it down faster. That is the trade off?

    Ah! That makes more sense. I was kinda thinking you just left the 1 off your numbers, wasn't sure. The difference between 125psi and 155 is noticeable. I'm not sure id even consider using 90. What size tank you running? 25cfm is a nice size unit. I'll bet it runs that blast cabinet 1000 times better.

    Hi Jeff
    Yes one of the main reasons I got the 80 gallon tank unit is for the blast cabinet and the soda blaster I have. Most tools run at 90 PSI but I have the main regulator set at 90 PSI Static Pressure. Do you run your tools at 90 PSI working pressure? What would the static pressure be set to obtain that?

    The shop i used to work at, the main compressor gauage read about 155. No regulator iirr, thats just where the cut out switch was set. Line pressure at the tools couldnt have been much less. My bays where right next to the compressor. Never ran regulators off the main line for individual tools. My 1/2 impact lasted 15 years and Lord knows how many gulps of water. The shop didnt have a drier system and had a hard time remembering to drain the tank nightly. :hair:

    That is interesting, since I have just a small shop, I have a regulator water filter on the main line but also have a large desiccant air dryer before it, so I can increase that main pressure and then I will put a small regulator pressure Guage on my impact drop so I can adjust it to 90 PSI working pressure. Will that work out?
    I got new tires and the tire shop cranked the lugs on wicked tight! I bet they do not have regulators or torque sticks for their impact wrenches!@&$@&@ :-( ??

    No matter what you do…bigger couplers, larger diameter or shorter hoses feeding it, fewer bends in the line… It all adds to the amount that will come out of the hose. Your higher demand stuff will work more properly at the expense of the compressor running more
