    No-Spill® Fuel Containers

    No-Spill® fuel containers advance convenience and quality in gasoline-can design by reducing emissions of hydrocarbons from evaporation, permeation and spillage. This helps protect the environment as well as saves you on fuel costs due to waste. Each container is molded from fluorinated, high molecular weight material for low permeation. The thumb-button flow control allows filling even smaller-sized tanks reducing the risk of spilling and is designed to stop the flow automatically, when the tank becomes full, to prevent overflowing. Built on a wide, stable base for less likelihood of upsets and equipped with child-resistant closures, all No-Spill® containers comply with both EPA and CARB requirements.
