Reservoir Tank for Air Compressor

Hello All:

I'd like to use my 4 gallon air compressor occasionally for spraying paint with a Wagner Conversion spray gun. Thought it would be necessary to add a reservoir tank between the compressor and the spray gun. However, the tanks I find readily available are called "carry tanks" and it's not clear to me how the connections need to be made. The carry tank has a standard 1/4" threaded output fitting, but the air intake is a threaded piece that looks like a tire valve stem and includes the pressure control knob. Advice as to needed fittings will be very much appreciated.

Ignore the air in a pressuree control valve, just put a T at the output fitting, one side to compressor, the other to the device your using. set the pressure on your compressor and have fun

According to vernal888 :

"Carry tanks" (aka "air pigs") are designed to be filled at the local gas station off the tire pump, and carried home for refilling other tires... Shrader valve (tire valve stem) in, hose -> shrader valve out.

The ones you see are a bit different.

In my case (shrader in/shrader out), I unscrewed the original manifold from the tank (1/2" NPT). Then did something like: mount a 1/2" iron tee, with the original manifold off one leg, and some 1/4" female NPT for standard fittings.

It's usually possible to buy a suitable distribution manifold for not much money, or, make it out of copper plumbing pipe.

That was the first generation with a 4 gallon "air pig".

The second generation was with a 10gallon "air pig", where I made the new manifold out of brass, including a home-made one-way valve and pressure switch, and mounted it on a cart. Turned a tankless compressor into a 10gallon tank type.

Thread a Tee onto the 1/4 fitting. One side of the Tee to your compressor, the other side to your air device.

Great idea, sir!

According to Chris Lewis :

I realize now probably somebody will yell at me about using home-made pressure fittings and how dangerous they could be.

You haven't seen mine ;-) Minimum 3/8" brass wall thickness. Probably good to several thousand PSI.

The manifold weighs well over a pound (bored/turned in 1 3/4" round bar stock), and the one-way valve (bored/turned 1 1/4" round) not much less.

It's kinda pretty in a brute-force sort of way ;-)

Good way to waste an afternoon in a machine shop with some brass bar stock I picked up at an auction for a few pennies per pound, a spring, and a delrin faucet washer.

Okay, okay, a few thousand PSI would probably destroy the washer and it'd leak.
