This 1.8 gallon (7.5L) heavy-duty liquid storage tank is constructed with linear low-density polyethylene (LLDPE) using one-piece molding technology, ensuring exceptional durability and leak-proof performance. The press-in threaded sealing cap and upgraded anti-leak design effectively prevent spills even under vigorous shaking or inversion. The built-in adjustable flow-rate self-sealing spout and anti-backflow air valve enable smooth and efficient liquid transfer. Equipped with tubing seals and rubber rings, it offers wide compatibility with motorcycles, UTVs, ATVs, SUVs, trailers, and off-road vehicles. Unlike traditional split designs, its seamless one-piece construction enhances structural strength for reliable performance in demanding conditions. The package includes 1× 1.8 gallon (7.5L) tank, 1× built-in spout, 1× faucet (Note: Lock not included, must be purchased separately).
