Polyurethane Hose – Sometimes referred to as poly hose, polyurethane air hose is considered an “all-around” option. It weighs less than comparable hybrid and PVC options, which is a factor you'll appreciate after you've dragged it around a job site all day.

Air hoses can supply power to cylinders and vacuum pumps as well as funnel compressed air to jackhammers, staplers and impact tools. They can even be used to provide vehicle functionality for mobile equipment and can also be used in areas of agriculture, mining and drilling.

In summary, polyurethane hose outperforms rubber hose in every category except when it comes to pliability and the ease of coiling it into a circle on the ground or forming a uniform wrap on a hose reel.

Air tools that require a lower 1-3 CFM such as a nail gun, usually work well with a 7mm hose. Air tools that require a larger CFM such as an ½” impact wrench will require a minimum of 10mm hose to run at full capacity. The air tool manufacturer will usually list the minimum hose size on the tool's specification.
