303VKIT HIGHFLOWPRO Coupler & Plug Kit V-Style 1/4 NPT Purple - 3 Pieces

These are the best couplings I have ever used on air hoses. They offer an air tight connection, zero leaks, literally zero. They also offer 1 handed operation when connecting/disconnecting tools. They are aluminum and don't hold up as well when being dropped on concrete shop floors, BUT, even so, they do hold up well, they just get scratched/dented up a bit, but still work great (although ugly). You get more power at your tools due to the high flow, I mean noticable power. Your impact can remove bolts/nuts that it couldn't before. More air delivery means all your pneumatic tools are more powerful. Try these, you will not be disappointed, but remember, you need to use only these fittings from from your air compressor to your air tools, if you have and regular couplers in between, you will not get the higher flow. ( a chain is only as strong as its weakest link)

Theee things really do flow like you have the connectors one size larger. This is done because they’re aluminum, which can be thinner wall and still maintain the structure. This allows the outside diameter to be the same (and therefore the female end is compatible with the typical coupler), but the internet side diameter is significantly larger, flowing more air. I do see more wear than a typical conductor, downfall of using aluminum. These tend to drag on the floor a lot, which will wear faster due to the material. The flow and backwards compatibility is worth it though. I have couplers 20 years older and chances are these will have to be replaced every couple of years, due to this wear. However, I think the ends still justify the means and therefore is still rate these five stars.

Like the color, worked flawlessly

What a difference! All of my air tools have incredibly more power than with the standard M connectors. Definitely a good choice!

female dosent shut off when removed unless you smack it hard to connect at times the higher flow is a vast improvement and worth the fuss as others note these are not heavy use construction

Great affordable option for impacts but my matco air hammer destroys the male part of the fitting.

Great for impact gun. Much more powerful.

-Nice flow -Soft aluminum can't hold up short term. Let alone long term -Looks pretty, until you use it - after one month use holding crest land reduced from .052" new to .026" new. Get steel v style instead. -Sory Milton, this is a fail

Bonjour, après plusieurs mois d'utilisation toujours fonctionnel et étanche. Léger et suffisamment solide pour un travail en amateur comme moi. Peut être qu'un professionnel voudrait du métal plus épais.

cumple su proposito

These are sturdy and flow really well. The female coupler will even receive other sizes which come with some tools. See pic 2 and 3. Handy if you can't switch to the V line entirely. Put them on the gobblers and leave the small ones on your low consumption tools. Put these on one of those flexilla hoses and you'll never look back!

Fonctionne très bien pour moi qui utilise à l'occasion . Je ne le recommande pas pour un usage intensif

It super charged my air impact gun and my die grindr as well as my Cut off wheel. Just make sure to replace all the fittings from the tank as well.
