Composite Gas Tank
See-through tanks let you check levels.
Having had our propane supply run bone-dry at the worst possible time, we were drawn to the translucent composite liquid propane gas (LPG) tanks, which recently gained the approval of the U.S. Department of Transportation (DOT). The new tanks do not corrode and allow the user to see remaining fuel. We found two types: Ragasco one-piece blow-molded tanks made in Norway, and two-piece molded tanks (with a seam joining the top and bottom) made by Lite Cylinder Co. in Franklin, Tenn. We obtained a 9-kilogram Ragasco tank from distributor Trident Marine (www.tridentmarine.com) for testing and noted that its dimensions (12.5 inches in diameter by 18 inches high) differed slightly from that of its 20-pound aluminum or steel equivalent. The tank may not fit in some propane lockers. The dimensions for the composite tank are actually smaller, but it is broader at the top and bottom.
