Hexagonal Nut Fitting compatible with Fuel Transfer Hose - Plastic Thread - compatible with Cans, Tanks and Pumps

Replacement gas tank nozzle, fits most 1/2/5/10 gallon gas tanks. We offer 6 threaded collar caps: 3 coarse threads and 3 fine threads. As shown in the image, the internal thread size is 1-3/4"-1.7 inches and can only be used with gas tanks that have a 1.7-inch tank nozzle size. Please measure your fuel tank nozzle size becompatible withe purchasing. The newly improved coarse thread gas nozzle cap reduces the height of the cap to ensure a complete seal. High-quality material: These air tank nozzle replacement parts are made of high-quality HDPE material, which can be bent freely without breaking during use. The thickened and widened rubber seal fits the bottle cap better and prevents liquid leaks during refueling. Anti-splash design (note: as shown in the image, the gas bottle's screw cap is hexagonal). The nozzle tube and nozzle cap are threaded, and there is a rubber sealing ring inside the nozzle cap. Tighten the nozzle cap after use. No oil spillage during transport or if dropped from the tank. This can cover more oil tanks. We provide two types of fuel tank vent caps: A) compatible with tanks without a vent at the end, simply drill and install. The B vent cap compatible with the gas tank is designed compatible with use on another gasoline tank with a vent cap at the end, replacing the old vent cap. Easy to install.
