Firestone 9481 3-Gallon Air Tank - Four 1/4" NPT & One 1/8" NPT Ports, 150 PSI

The Firestone 9481 is a 3-gallon steel air reservoir tank designed to provide a dedicated source of compressed air for air helper spring and air suspension systems. By storing pressurized air on board, this tank allows for faster inflation of air springs compared to relying solely on a compressor, improving system response and leveling performance.

Constructed from steel with brass fittings, the tank features a baked black enamel coating applied both internally and externally for maximum corrosion resistance. It is manufactured to SAE J10 specifications and pressure-tested to twice its working pressure, delivering a rated maximum of 150 PSI.
