Product description
ColorFit by Milton Industries- 14 Piece V-Style HIGHFLOWPRO S-314VKIT Coupler & Plug SetStop starving your tools of the air they need to perform. More torque and greater speed are just a couple of the benefits possible with ColorFit by Milton Industries’ 14-Piece V-Style HIGHFLOWPRO Coupler & Plug Set. This set now offers a customized color-coded system that allows for easy matching of couplers and plugs, among the range of standard Industrial pneumatic air coupler quick connects. Great way to solve that annoying problem of potential cross-contamination between different air lines. By dedicating certain colors to different air lines, this will eliminate the risk of mixing a lubricated line with a dry air line which will prolong your applications and help to quickly finish any project. Each piece coated with Anodized Purple aluminum and heavy duty steel sleeves to prevent scratches or dulling of the coupler and plug after use. Compare to Legacy Flexzilla A53458FZ.MORE POWER WHEN YOU NEED IT: High Flow PRO couplers and plugs deliver up to 70% more flow to deliver more power to your air tools.

- Reviewed in Canada on April 21, 2021Verified PurchaseWorks as advertised. There’s actually more air flow. Even from my small efficient 20gal. And when I measured the inside diameter, it’s noticeable larger. Gonna see how they test with my LVLP or HVLP spray guns.
Now I just need to replace all my tools in my garage. May need to get another pack.
Top tip- make and quick fit adapter by fitting a regular adapter to one of these. In case you want to use another tool that doesn’t have one of these or using someone else’s tool.
- Reviewed in Canada on February 22, 2024Verified PurchaseI got a bad batch initially that leaked, amazon sent me a replacement right away. Over all satisified. These are made of aluminum so they will wear much quicker then steel fittings.
They're being used in an auto detailing shop environment, so i'll update the review at a later date
- Reviewed in Canada on March 31, 2022Verified PurchaseFit and finish is excellent, can tell the tools are working much better with these over the M style. The only issue I have is with the aluminum plugs, one of them seems to be galling up from the detent balls in the coupler. Would be ok for the hobbyist or home mechanic, would recommend the steel plugs for any heavy use.
- Reviewed in Canada on March 8, 2021Verified PurchaseI had some fittings (I think they were M type) on the smaller compressor I purchased from Canadian Tire. But they didn't match up with some fittings I had on some tools I inherited from my dad. Plus I noticed that it seemed to take too long to fill up some tires with air with the old fittings. Researched different types of fittings & decided to go with high flow V fittings, which these are. These are nicely colored, so I can see at a glance that the tool I want to use is compatible with the fitting. I used a fair bit of teflon tape to seal the threads when I installed them, & the compressor holds air a lot longer now than before (probably my fault before).
- Reviewed in Canada on June 24, 2025Verified PurchaseWorked good, good value.
- Reviewed in Canada on October 10, 2023Verified PurchaseThe media could not be loaded.
- Reviewed in Canada on October 26, 2022Verified PurchaseThe plugs are really thin metal, very light, almost plasticy. Purple paint starts to wear off pretty quick. But I havent had one break on me yet. The couplers are better quality, the quick connect always works, and they take both purple and regular M plugs. Only issue you'll run into is if you dont use the purple couplers at every point in your air compressor setup and ditch regular couplers completely, you're going to run into the problem where you need to switch out a coupler because while the purple couplers will take both the purple plugs and regular M plugs, the purple plugs don't fit into anything but the purple couplers.
So plan your setup accordingly, or buy extra purple couplers and go full high flow everything.

Reviewed in Canada on September 15, 2024Verified PurchaseVolume d'air bien meilleur qu'avec des type M. Les coupleurs sont en acier et les plug en aluminium.
bon produit pour le prix.

5.0 out of 5 stars Excellent Kit for High Airflow Needs
Verified PurchaseThis Milton S-314VKIT is a fantastic upgrade for anyone needing more airflow from their pneumatic tools. The V-style fittings deliver noticeably better performance compared to standard connectors, especially with high-demand tools. Everything in the kit feels well-made and durable, and the purple color makes them easy to spot in a busy shop. Great value and performance—highly recommended for serious DIYers and professionals alike.
