Our 4-gallon pancake 8 port air tank is perfect for sports cars or compact cars where space becomes a big factor. We find they fit snuggly in cars’ spare tire compartments. On trucks, they fit nicely under the bed for a clean, low-profile appearance. This tank features eight ports: four 1⁄2” ports on top, two 3⁄8″ ports on top, one 1⁄8” port on top, and one 1⁄4” port on the bottom. Giving you a lot of options when plumbing your onboard air system. Built for the road, the 4-gallon air tank meets SAE J10 and FMVSS 121 specifications and comes in a black powder coat finish to resists corrosion.

As an important safety precaution,  a safety blow-off valve should be installed with any air system. A safety blow-off valve is designed to keep the system from over-pressurizing and to prevent damage to other components. It is suggested to use a safety blow-off valve with a PSI rating between 25-35 PSI higher than the maximum pressure of the pressure switch.

For example, 150 PSI systems require a 175 PSI safety blowoff and 120 PSI systems require a 150 PSI safety blowoff.
