Get big performance in a compact package with our 4-Gallon Pancake 8 Port Steel Air Tank. Designed for vehicles where space is at a premium, this flat, space-savvy tank fits easily into spare tire wells, under truck beds, or other tight spots without sacrificing air supply. Built from heavy-duty steel and finished with a semi-gloss black powder coat, the tank is protected inside and out against rust and corrosion thanks to an internal rust inhibitor. Its eight-port configuration—including four ½″ NPT ports, two ⅜″ NPT ports, one ¼″ NPT port, and one ⅛″ NPT port—provides unmatched flexibility for customizing your onboard air system. With a 150 PSI working pressure and 750 PSI burst rating, this tank delivers reliable power for train horns, air suspension, or air tools. At just 16″ wide and 8″ tall, it's compact enough for discreet installs but strong enough to handle demanding pneumatic setups. Proudly made in the USA and compliant with SAE J10 and FMVSS 121 standards, this tank is engineered for performance and durability you can trust.
