Air Fittings That Do Not Leak?

[Contract_Pilot]

Looking for air fittings that do not leak! Anyone have a good Brand?

 

[HemiRambler]

Last ones I bought from McMaster_Carr were really nice. At the time they were cheaper than the Horrible Fright ones were!

 

[softailgarage]

I buy the cheap ones from HF and don't have leaks. I tried the expensive ones from the tool trucks and had nothing but problems. Are you using Teflon Tape on the threads?

I use Dixon brand couplings and am very pleased with them. https://www.dixonvalve.com/product/2DM2-B

I have to admit I use HF couplers and plugs. I never tested them with soapy water, but I can't hear any leaks.

Milton always get high marks.

Lowes here. Hf fittings leak like a sift. Never had any luck with them. Or air chucks. I have some old milton fittings that look wore out and seal better than new.

 

[Mr.3-5-7]

One of these...

And one of these...

ive been using this combo on all air fitting for years and never had a problem.

 

[djjsr]

Milton, males and females.

 

[tdkkart]

Another vote for Milton.

 

[ZRX61]

Milton again.

Hey, has anyone mentioned Milton yet?

Milton stuff can be a bit hard to find -- I've found Milton goodies around here in Rural King (farm store). Some independent auto shops that cater to pro mechanics carry Milton.

Napa used to carry some decent pneumatic stuff, but they switched over to the cheapo commie junk a few years back. Might as well go to HF and get it cheap.

That said, about three out of five HF fittings work fine. Leaky stuff gets tossed into the metal bin immediately.

I use Milton 777.
You need to replace ALL the couplers & ******* at the same time.
If you just replace 1 or the other, the other part is always wore & will ruin the new part that much faster.

 

[b-body-bob]

I just replaced all my random sourced 1/4 universal interchange fittings for C-H 3/8 automotive fittings from Tractor Supply, and got rid of all the hissing connections that always drove me nuts. I've only used them once to impact some bolts out and back in but the impact seems stronger with the added volume too.

 

[Cryptic1911]

Milton, males and females.

Yup, get some milton v series high flow fittings

 

[Spareparts]

I changed my female ends from a horizonal position to a verticle position, the hose coming straight down instead of straight out side loading the coupling. So far it seems like they last longer, but the jury is still out.

Milton M style couplers are $7.88 at Amazon.com

 

[djjsr]

You can also find Milton fittings sometimes at good prices on ebay. Just beware that some listings may say Milton design or Milton type and they are not manufactured by Milton. I would not buy those.

 

[gungatim]

another vote for milton 777's. switched my tools out back in the 80's when I worked in a body shop. they never leak, and every factory I have worked in since uses these as well so I could always scrounge a few. side benefit is nobody every borrows my air tools at home because they all use the cheap homeowner **** and mine won't fit!! BTW, 777's come in a nice kit with a female and several males for under $10 at my local farm and fleet type store.

 

[cagullett1]

I got my Milton fittings on Amazon at a very reasonable price. Cheaper than Northern Tool or Ebay.

Milton M style couplers are $7.88 at Amazon.com

I am getting old. Used to sell them in the mid 90s for 2.19 male 2.89 female. You can't hardly get china for that price now. I feel like im turning into my dad. Hahah

 

[djjsr]

10 sets, male and female, Milton M style Ebay item 231141236487

$49.40 with shipping.

Speaking of fittings, I recently bought a Bostitch stapler and it has the fitting that has a swivel in it. I have never used one like that and I really like it. Anybody else?

As far as leaks go my HF stuff does ok. You do get a dud some times though.

 

[kesslerbmw]

Milton and or Prevost are the only ones I'll use, and I always use Teflon tape on the threads. I ALWAYS use Milton *******, and for some of my hoses I run Prevost couplers.

 

[Contract_Pilot]

Thanks for the advice..

 

[stage20]

I changed my female ends from a horizonal position to a verticle position, the hose coming straight down instead of straight out side loading the coupling. So far it seems like they last longer, but the jury is still out.

id believe this is true. on my hose i use the most on my lil pancake compressor, it hisses hard and i can turn it and it quits leaking. no different than one side of your car key that gets worn down more than the other side. LOL.

im going to setup my air couplings hanging down in the shop and see how it goes. i havent gotten around to plumbing it yet. just finished most of the electrical, still need to wire compressor too.

I have to admit I use HF couplers and plugs. I never tested them with soapy water, but I can't hear any leaks.

Milton always get high marks.

I got a batch from HF and they were fine (except for one plug that didn't have any hole through it). The next batch I got leak, not through the threads, but where the coupler and plugs connect. They don't leak if they are perfectly aligned, but they do in normal usage.

 

[The Cobbler]

for the female coupler I use Milton. tried el cheapos and after a short while they leak . plugs on the other hand I use anything. Homeowners probably can get away with cheepies, but when you're using them all the time spend some coin & you won't be disappointed

 

[6768rogues]

Steel not brass. I have not had good luck with brass male fittings.

O'Reilly's can order Milton fittings, usually takes a day to get, at most, unless it's on the weekend.

Napa used to carry some decent pneumatic stuff, but they switched over to the cheapo commie junk a few years back. Might as well go to HF and get it cheap.

That said, about three out of five HF fittings work fine. Leaky stuff gets tossed into the metal bin immediately.

A quick bit of math on HF fittings says that after throwing away 40% of the garbage, you've closed the gap between the cost/fitting between the junk and that of Milton V-Style fittings. In terms of which flows better and will last longer, it's not even a fair fight.

 

[williammcneely]

If you are talking about quick disconnects I use Prevost. Been using them for years they hold up very well.

[kapster]

I switched to milton high flow after getting tired of leaky cheap fittings and couplers. There have been great.

Don't remember where I read it, possibly from milton, but you should use a whip hose on impacting tools instead of the fitting directly on the tool. Keeps the impacts from wearing on the fitting and coupler.

 

[tshetter]

Milton Type-V high flow.

 

[chris142]

The hf fittings ****. The balls make grooves in the male part then they leak. Amflo stuff is much better

 

[gtermini]

For the High Flow (European Interchange) users out there, here is the best deal I have seen on the plugs.

10 Females $17.98

10 Males $19.33

[Will Wrench]

Prevost

 

[theamcguy]

Northern carries Milton, if you have a store nearby.

 

[LS6 Tommy]

Yup, get some milton v series high flow fittings

X2. Switching to the V fittings made a very noticeable difference in tool performance.

[cousin eddie]

Can you use the v-style on anything? I thought they were high flow, but low pressure
