HONK YOUR HEART OUT
This expertly designed steel air tank is a linchpin for a multitude of pneumatic applications, whether it's air horns, air suspension, or onboard air systems, acting as a reliable hub for your air supply.

With a versatile configuration of seven 1/2" NPT ports and a singular 3/4" NPT port, this tank affords a plethora of connectivity options to cater to your system's specific demands. A robust maximum working pressure of 150 PSI, coupled with an internal rust inhibitor coating, fortifies the tank against the rigorous demands of high-pressure pneumatic operations, promising a sustained, reliable performance.
- Versatility & Power: Designed for a wide range of onboard air tasks, this air tank is perfect for load leveling, tire adjustments, and is compatible with premium train horns including Nathan AirChime and Leslie models.
- Enduring Design: Aesthetically pleasing and durable, the sleek black powder coat is enhanced by an internal rust inhibitor, ensuring long-lasting protection and performance.
- Certified Excellence: Manufactured in the U.S.A., this air tank complies with SAE J10, FMVSS 121, and DOT standards. With a solid 150 PSI max and an incredible 750 PSI burst rating, it delivers both safety and efficiency.
- Reliable Warranty: Rest easy with a 2-year manufacturer's defect warranty that validates the quality and reliability of your investment.
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.
