Our 7500 Series 5 Gallon Adjustable Vent Jugs are high-strength industrial designs made from chemical resistant high-density polyethylene. Dual molded body bands help with container swelling, keeping fluid level marks more accurate. The Tri-Ribbed bottom adds strength and also doubles as a multi-grip pouring handle. Every jug goes through a multi-point inspection, including pressure testing, and carries a 3-year limited warranty. Race Jugs are available in 10 colors, several different package quantities, single pack, two-pack, or four-pack cartons.
