FlexzillaPro High Flow Coupler & Plug Kit, 1/4" NPT, 7-Piece - A53457FZ

I got these to go on the ends of my 3/8" Flexilla air hose. They fit perfect and are good quality.

I have installed several of these on my air tools. The swivel makes it a lot more comfortable to use them and this one does not seem to reduce air flow or leak. Will buy more when I get more air tools. Every one of my tools needs one.

I needed to replace my fittings and these did the trick.

I bought it to compare to my other favorite brand, which suddenly went to a cheaper quality to save money, and had nothing for knurled sides so impossible to unchuck with one hand. This brand easily unchucked with one hand (pressurized), accepts all of my other chucks, but offers the higher flow options. Gonna put it on all of my hoses.

These fittings are well made & lock together very smoothly with no leaks. Threads are cut well & gave no trouble when tightening. Vastly better quality than the cheaper brands I've tried.That being said, the packaging is terrible. The fittings come sealed between a cardback & plastic cover. The problem is, these fittings are heavy & the adhesive holding the packaging together is weak. The first package I received was busted open & missing 3 fittings. The replacement item was open as well, but fortunately all the parts were in the envelop. The parts got scuffed up rattling around but I count it as a win that I didn't have to reorder a 3rd time. For the price you pay, it'd be nice if Flexilla would give you a plastic case to store them in. Or at least fix the packaging, then they'd be worth 5 stars.

Highly recommend for higher cfm flow. Will drain a small tank capacity so you may need to increase your tank size. Be sure to get enough fittings for all hoses, compressor and attachments. I had to get 3 packages for all my air attachments and hoses. Total 16 gallon capacity. Hitachi twin 2.5 gal tanks with add on 11 gallon tank.

Exactly what I was looking for, gives the tool some movement on the hose. This one does need the high flow V style coupling on your hose. These seem well made and action is smooth.

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.

The swivel improves the maneuverability of the HVLP gun and the airflow improved over the regular coupling. No leaks after a few months of use. Would recommend.

El producto es bueno a comparación con los comerciales que vende en cualquier ferretería, me gusta que tiene más flujo de aire y eso se refleja mucho en el uso de herramientas neumáticas y en el uso de pistolas de gama alta para el repintado automotriz.Un detalle que no me gustó es que llegó todo regado en una bolsa por qué el empaque estaba roto y se rallaron y pense que eran usados.Por lo demás es un producto que se ve de calidad y que da buenas ventajas , llega a tiempo y a buen precio.

Epic fail in not indicating they were not Nitto style fittings. very average construction.

Good quality and fast ship. Thanks

Covers everything by the compressor. You get both ends of the hose and one tool but you will need to buy another coupler for the compressor.
