I picked up one of these units & tubing at Lowes today. 9 bucks for a good combination!
This pays for a fancy bleeder plus enough left to contribute to this website. I am building a composite but I still have fond memories of sheet AL.
The Glasair site costs $35 a year....

Won't fit
I have the Chapin sprayer, the 1/4" ID, 3/8" OD tubing, and some 1/4" OD static line tubing.
I can't get the tubing over the end of the sprayer (the brass fitting on the sprayer is too big, it measures 11/32". How did you get that to fit?

I've got one of these in my garage somewhere that I used to use to bleed the brakes in my old 80's sports car. I wonder if it could be adapted to do the job on the RV once it's together...

You will need a larger hose on the sprayer tip, then using some small bore rigid tubing of your choice to join the larger to the smaller. YMMV, but with the chapin unit, it somehow sucked in air when I tried it, went to oiler can with 1/4" tubing and worked like a charm. Butch

Sure can Ryan, I have been using the sprayers for a decade(+) and broke down and bought this one. After using it on my truck, I actually liked the sprayer better. This unit as a restricted exit flow. Now I have a different bleeder for each fluid.
It will do just fine on the plane as it will be flowing in the same direction as the bubbles. Actually easier to bleed. Just put a 1/4" poly tube on the reservoir exit to catch the excess.

I've had no luck getting a standard grease coupler to work with the Matco brake zerks (ie brake bleeder). Just not enough depth to get the coupler teeth to grab.
Anyone using a coupler (part number?) that works on the Matcos? I can do the standard "jam the tube on" but liked the positive atch of a coupler.
Guess not all brake bleeder fittings are created equal......

I snipped off the tip and used a 1/4" x 1/4" barb to join the sprayer wand to the 1/4" ID tubing. It is a little snug fitting the barb to the sprayer wand so I drilled out the ID just enough to make it easier with the help if my heat gun. No leaks.
