## Description

Stop 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’ 3-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 A53452FZ.PACKAGE CONTENTS: 1 Male Plug 1 Female Plug 1 Female CouplerMORE POWER WHEN YOU NEED IT: HIGHFLOWPRO couplers and plugs deliver up to 70% more flow to deliver more power to your air tools. Great for paint spray applications, sandblasting, high CFM blow guns, and more.PUT COLOR TO USE IN YOUR SHOP: Easily match couplers to the right plugs using color, (purple to purple)- no more guessing. Use color to distinguish between air lines, such as lubricated vs. non-lubricated, or high pressure vs. low pressure.SUPERIOR PRODUCT DESIGN: Durable patent-pending steel sleeve design outlasts the competition by putting steel where you need it most. Milton uses an advanced, proprietary anodizing process.COMPATIBILITY: ColorFit V-style couplers and plugs are compatible with traditional Milton V-style couplers and plugs, and competitor V-style couplers and plugs. All threaded connections are 1/4"" NPT.SPECIFICATIONS: Do not exceed 300 PSI. For use with compressed air only.**Disclaimer: MILTON INDUSTRIES is NOT affiliated with Legacy-ColorConnex- X-Flo # A73410D, ColorConnex A73420D, ColorConnex A72640C-X, ColorConnex A72410C, ColorConnex A72420C, or Legacy Flexzilla.

Review: The best couplings I have ever used, period. - 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)
Review: Excellent flow - 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.

## Features

- V-Style: Milton V-style, ColorFit V-style, + competitor V couplers/plugs are all compatible!
- Durable: Scratch-resistant steel design in an anodized coating for optimal wear vs. aluminum sleeves
- Color: Purple to Purple matching - (V/High Flow) air coupler/plug fittings, easy push to connect
- Includes: 1 Male plug, 1 Female plug, + 1 Female coupler (all 1/4" NPT)
- Disclaimer: Not recommended for use with high vibration tools (impact wrenches, orbital sanders, etc.). Also, use of these couplers with a leader hose will extend the lifespan of the product further
