What Can Be Used Within the TCP Global Paint Tank?

Unlike some other tanks by competitive manufacturers, the TCP Global Commercial 2.5-Gallon Spray Paint Pressure Pot Tank is capable of managing a broad range of coatings.

This pressure pot spray gun handles varnish, lacquer, wood coatings, oil-based paint, and latex paint. It is strong enough to apply adhesives, but still has the precision to apply automotive paint.

Four clamps work to ensure that the correct pressure is maintained within the tank itself. An air pressure relief valve is equipped to ensure users have the most possible control.

You can use several different products within the tank as well. It works with most 2.5-gallon tank liners.

You can also use paint buckets or paint cans that are under 2.5 gallons with the tank. In the box, it comes with a removable 2-gallon aluminum fluid liner bucket.

Users can even remove the easy-roll casters if they prefer to have a stable base of operations.

How Well Does the Pressure Hold Up Within the Paint Tank?

Many users have commented about the ability (or inability) of the TCP Global Commercial 2.5-Gallon Spray Paint Pressure Pot Tank to maintain pressure levels while unattended.

We pressure-tested the unit for 7 days to see how well it would operate. The paint pressure tank tank loses about 1 PSI per day, on average, but tends to lose a little more at higher pressure levels.

Our Issue with this TCP Global Pressure Pot Sprayer

Our one area of concern is the positioning of the valves. They’re a bit awkward and there’s no real way to get a fix done to provide some relief.

You can read the pressures just fine, but the actual valve position can be difficult to see with this design.


For an inexpensive pressure tank, the TCP Global Commercial 2.5-Gallon Spray Paint Pressure Pot Tank provides a ton of benefits for large-scale solutions.

If you’re ready to step-up from HVLP or gravity-feed sprayers, then invest into this product and you will be impressed with what it can do.
