Looking for an alternative to your traditional round tank? Look no further; these Square Tanks are designed and manufactured in the USA, and are sure to add a little flair to your trunk setup. What really sets them apart is the port location on the backside of the square end caps, meaning you get a show worthy tank, and no visible connections from the front!

If you're looking for a different size, be sure to check out the 5 gallon version!


  • Square end caps with connecting rods, for a unique look and to ensure an airtight seal
  • The square endcaps feature ports on the backside to hide all your connections for a sleek look
  • Designed & Manufactured in the USA
