Air Tanks

Whether you're building an air suspension setup, plumbing an onboard air system, or installing a train horn, the air tank is the foundation of your project. Our collection spans steel and aluminum tanks in a variety of capacities, port configurations, and pressure ratings to match your application.

  • Steel tanks offer robust construction and corrosion resistance for high-pressure, heavy-use environments.
  • Aluminum tanks provide a lightweight alternative ideal for weight-sensitive builds and clean installations.
  • Key specs to compare: tank capacity (gallons), max working pressure (psi), port sizes (typically 1/4" to 1/2" NPT), and overall dimensions for mounting.
  • Many tanks include drain ports and mounting brackets—check individual listings for included hardware.

Browse by size, material, and port layout to select the air tank that fits your air ride, suspension, or horn system.
