Brass 1/4 Inch NPT High Flow Air Coupler and Plug Kit, Air Hose Quick Connect Adapter, V Style, Air Compressor Fittings, (28 Piece)

I use my air everyday and highflo does make a difference. I seems I have to replace these fittings a couple times a year and these seem to hold up better than milton.

works like it says it should

These fit and thread perfectly, the couplers work great no leakage with heavy all day plug and release with no issues and overall best value for the money. I'm going to purchase this brand again when the need comes back around.

Great idea. Not highest quality but functions ok.

I always bought the quick connectors from any of those big box stores and they always started to leak after awhile, you also needed a second hand to make or separate the connection from a wall unit. Than I found those, just push the male part into the coupler (no sleeve/ring to pull back). I disconnect push the ring/sleeve back and the male part pops out, both ways with on hand (wall mounted coupling). You can even fix them if they start leaking..... if. Before those I couldn't let my hose connected, the coupler started to leak after a few month from the weight of the hose. My hard piped system in my garage is absolutely airtight and now with the air hoses still connected no loss either. The longest time between using the air system was 3 weeks with an air pressure of 80psi all the time. With the old fittings my compressor started every 24 hrs.Best of all is the price, same price like the parts from the big box stores.

I at first loved these, lots of air and easy change from air chuck to blower. Now it takes 2 hand sometimes to pull back the quick release to release an attachment( this is when the line pressure is set to over 90lb). Once in a while, when I remove a tool , it just blows until I whack the coupler. I have not had the o-ring come out yet. I know couplers wear out , but these don't seem to last too long. Bad brass???

I'm not someone who writes reviews 6 hours after using a product. I like to really use a product to get a good solid feel for it and make sure it is worth the time to write a review. Having said that, I ordered these fittings to replace all of my failing Milton quick connect fittings March 2020. I have had these for over a year now and I am still using the original pieces that I installed. Prior to this, I had to constantly replace the Milton fittings at least once every couple of months because they would leak after disconnecting tools. I am a heavy user of pneumatic tools and by no means gentle. These fittings are not leaking and are holding up very well. I will be ordering more with the expansion of my air system. If anything changes, I will update this review.

Let's face it, this is an expensive fitting set. I bought two sets of 28 pieces. They had everything I wanted, quick connect, high flow, nice to look at., and all the fittings I needed to swap all connectors over.Fast forward a few months and I started having a very strange problem. With pressure on the line/fittings it's impossible to connect fittings. Only way it works is when I turn pressure to zero on my regulator. You can only imagine what a hassle that is! I do alot of automotive painting so am constantly unplugging a spray gun swapping colors etc. Have to walk all the way to the compressor to turn off air to reconnect whatever tool I'm using.I'm assuming the problem is the male/female quick connect couplers. Cannot just swap those out because they are not compatible with standard airflow fittings. I have been slowly swapping everything over to std flow fittings. Somewhat frustrating buying stuff twice because they arent up to snuff.This is my honest review; these are my experiences with these item/s.Cannot in good conscious recommend these. The 1 star is because they still look good.
