How To Make Your Own Keg Sprayer
Do you use pump up sprayers to apply your chemical? Do you get tired of pumping them after a couple seconds of spraying? Here is a simple solution for you, make your own keg sprayer. The kegs can be a little difficult to find sometimes, but will save you tons of money in the long run.
After you have the keg.. you need 1 of these
and one of these
One is for gas (or air) and the other is for liquid.
¼” ID hose as long as you want. I wouldn’t go any further than 100’ though. Get some hose clamps, teflon tape and wrap the teflon around the hose barb a few times, then hose clamp your ¼” hose to it.
Next, You will need something like this
, but a chem gun like this works good too.
I just like the pressure washing gun because of the versatility after the gun. You can use different length wands, angled wands, etc.
Then you will need some of these.
Play around with the size of the orifice (that sounds dirty, doesn’t it?) and see what kind of pressure works best for your needs.
That takes care of the liquid side.
For the air side, I made a little pig-tail for it. I clamped a short ¼” piece of hose to the fitting just like the liquid side then put a quick connect fitting on the other side to connect to an air compressor.
Note: you may want to put a check valve on the air side so no liquid can backflush into your air compressor as a just in case!
Be sure to disconnect from the stainless steel fitting after filling with air. Always clean all fittings and hoses after each job and they should last for a very long time. Something else to consider is only putting about 3-4 gallons of chemical in the tank before you fill the rest with air. That way, you will be able to dispense the entire contents of the keg without having to fill it again with air.
Always wear proper PPO when using these because they can take up to about 110 psi of pressure from your air compressor. Having something like that blow up in your face isn’t fun. Be careful.
Hope this helps a little.

Good Stuff Ant!
Merry Christmas to you and yours..
Thanks, bro. Gimme a call sometime, we need to catch up.
Great info Ant.
Our company has been using these devices for several years and we always use CHEMICAL RESISTANT HOSE with these as you may find that regular hose will become brittle and crack.
Great info on a piece of equiment that most cleaners take for granted.
