Flexzilla Pro High Flow Coupler & Plug Kit, 1/4" NPT, 14-Piece - A53458FZ

Good quality

I got these for my smaller hoses, been very happy with Flex Zilla hoses the past few yrs...and more recently their "Hi Flow" ends. Then I needed some ends for a 1/2" hose with 3/8 ends, so I bought a cheaper brand (4.5 star) of so called "Hi Flow" ends and noticed right away that their inner diameter is smaller than Flex Zilla. Both the off brand ends and some Milton "Hi Flow" connectors I bought had smaller inner diameter than these ! If you just run nail guns then maximum flow is not as critical. They'll run fine on standard ends. But if you are running tools that require torque and continuous flow, like air ratchets, impact guns, then you want the biggest inner diameter for the most flow, to get rated output from these type tools where YES, it matters. It's comparable to using a thin 12ga wire jumper cable to start a car vs a thicker 6ga jumper cable...yes the 12v is the same, but the thinner cable can't carry enough current...and while yes many things will work, like the dome light, stereo, even headlights... the starter would struggle. Same deal with some air tools that require enough flow, not just the right pressure. The Flex Zilla is more money, but let me save you the time and aggravation...just buy these . See my pics for reference. On the left is the wide open 0.291" i.d. flexzilla...on the right is an off brand with smaller 0.259" i.d. ...also not shown is a Milton Hi Flow which also measured 0.259 i.d. I'll be ordering Legacy Flexzilla 3/8 ends . note: shown in my pics are a 1/4 flexzilla and the other is a 3/8, but the male part that you push into the coupler is the same size...just larger inner diameter on the flexzilla.

I received my package and other than most of the items lose in the shipping bag, it was fine. No damage to product just not a perfect package. Caused some ??? in my head but after looking, they were fine. I removed my old coupler to the compressor and attached the new one. Fit was perfect. Fired up the compressor (it was empty as the 20 year old coupler I had on it was leaking) and no leaks. Very happy. Swapped out a connector on 3 of my air tools and hooked them up. No leeks and seems solid. I really like the push connection. Having to pull down on a ring to insert and remove a tool was cumbersome. The push on is great. You have to pull down on the ring for tool release and it pops right off. Some may not like that it kind of ejects the tool, but you should be holding on to it anyway so it shouldn't be a big deal. Overall my initial experience with these connectors is great. If they last, I will be a very happy camper. If not, I'll probably have to spend the big money and move over to the Prevost couplers and plugs. Those things are fantastic. However, for a home shop/garage I just can't justify $25 per coupler when this whole kit was less than that.

Great flow with these. A bit more expensive, but you don't want reduced airflow.

Unfortunately not made in the USA. Even worse, it should be labeled in large text that these are not compatible with standard quick couplers and that buying into these means being stuck with them when you need new couplers. Build quality otherwise seems good while the latching and releasing mechanisms are both well designed and manufactured. Durability TBD and I'm not sure how easy it will be to replace the o-rings when they fail, but that's future me's problem.

After some research these looked like a best option to improve the performance of my air tools. They allow more air volume through than other high-flow products which don't have quite as large inside diameter specs. These do cost more but they are built well and work well. I find them easy to couple together even if using non-high-flow fittings with them. The female couplers are great. Machining is precise, finish is great. After re-working my lines with these all the way from compressor I have no leaks at all. Compressor sits idle until actual demand is made as these fittings don't leak. I have a sweet new Astro 1822 1/2" Nano Impact Wrench which inspired my purchase of these high flows and that thing is a BEAST in part due to these fittings. Love them.

I've purchased several sets of couplings ever since I bought an air compressor a few months ago. This is by far the highest quality couplings I now have. It is a quarter inch, but the amolunt of space for airflow is superior to other brands because of the inner vs outer diameter specs. Additionally, when you make a connection, it is literally a snap. Easy on easy off. I replaced the connector that came with an $800 dewalt compressor with one of these fittings. The from the factory dewalt fitting was very finicky, and actually wouldnt take these flexilla fittings. The Flexilla fittings take all. Havent had a problem. As I said, easy on, easy off.

Bought them for a flexzilla hose reel. Other fittings i had leaked when air tools are plugged in. These are tight fitting non leaking fittings. Bought more to replace all tires my air fittings.

Tiene buen acadñbado los materiales se ven resitentes cero fugas vamos a ver que tanto resisten

التغليف سيئ

Jonction Gros Debit !

المنتج ممتاز جدا لكن تم تبديل بعض القطع ليست مطابقة لصورة القطع اذ لم يتم العبث بها تعتبر من الافضل بين المنتجات

Absolutely wonderful purchase. High flow was definitely a great upgrade. Good quality metals too, not soft like some cheaper versions. Great variety in package, really good for any air set up.
