Firestone 9539 Air Tank 3-Gallon 7in. x 20.75in. (2) 3/8in. NPT Ports 150 PSI Max

The Firestone 9539 is a 3-gallon steel air reservoir tank designed to work alongside an on-board air compressor system, providing a ready supply of compressed air for air helper spring and air suspension applications. By storing pre-compressed air, this tank reduces fill times when inflating air springs, improving system response and overall ride control.

Key Features:

• 3-Gallon Capacity — Holds sufficient compressed air volume to quickly inflate air springs on demand
• Two (2) 3/8 in. NPT Ports — Larger-diameter ports for efficient airflow in higher-volume suspension systems
• 150 PSI Maximum Working Pressure — Handles the demands of both light truck and SUV air spring setups
• SAE J10 Compliant — Manufactured and pressure-tested to SAE J10 specifications, tested to twice the working pressure
• Internal & External Enamel Coating — Steel tank is coated inside and out for corrosion resistance and long-term durability
• Steel Construction with Brass Fittings — Heavy-duty build quality suited for automotive and industrial applications
• Black Finish — Clean, factory appearance for under-vehicle or in-vehicle mounting

The Firestone 9539 air tank is an ideal upgrade or replacement component for air ride suspension systems, air bag suspension setups, and onboard air systems. Its 3/8 in. NPT ports make it well-suited for systems requiring higher airflow capacity. Firestone Industrial Products backs this tank with a 2-year limited warranty.
