1、Premium Material: These kits are made of premium plastic material. The nozzle is constructed in one piece, resulting in a longer lifespan and increased flexibility and convenience in bending. The thickened and widened rubber gaskets provide a better fit for the bottle cap, preventing any liquid leakage during refueling. 2、Anti-Overflow Design: Both the spout tube and the spout cap are threaded, with a rubber sealing gasket inside the spout cap. After usage, make sure to tighten the oil outlet cap to prevent any oil overflow during transportation or when the tank is down. This ensures your absolute safety during use. 3、Two Types of Gas Can Vent Caps: We offer two types of gas can vent caps. Gas can vent cap-A is designed for oil cans without a vent at the end. Simply drill a hole and install to use. Gas can vent cap-B is used for oil cans that already have a vent cap at the tail, and can be used as a replacement for old vent caps. 4、Wide Range of Applicability: The upgraded gas can spout kit boasts improved compatibility, accommodating oil jug mouth sizes ranging from 1.7 inches to 1.82 inches and making it suitable for most 1/2/5/10 gallon gas cans. 5、Comprehensive Set: Each set of the gas can spout replacement kit includes essential components to facilitate easy installation and efficient use.
