Did you ever stop to think as to why the hose going from the sprayer pump to the hand gun is 1⁄2" inch? Most sprayer manufacturers install 1⁄2" inch 600 psi hose as standard for the handgun. Some even put in 5/8" and 3/4" hoses and these can be up to 50 to 100 feet long.

It does not make much sense to have such a large caliber hose carrying all that water when the nozzle at the end of the spray gun is only about 1/16" in diameter. So the hose really should be as small as practical without causing friction losses or bottlenecks.

Generally, the size of hose that works best for hand guns and spray wands is 3/8", 600 or 800 psi, depending on how you spray. This hose is not only cheaper than the 1/2", but also has better working and burst pressure factors. It is flexible and lightweight and, because it is carrying less water, not only is easier to handle while spraying, but gets less wear and tear through abrasion when being dragged along the ground, because of its lower overall weight.

Another bonus is that your can get up to 30% more hose onto on a standard reel, and, if you only have a rack to coil it on, that is also easier and lighter work. So look at your hoses; and the next time you have to replace them, think of going with a smaller size and lightening you or your employee’s load.
