Locking the gas cap is part of the emission control system that keeps the fumes and emissions of diesel and gasoline in the vents without exposing them to the climate or weather outside. And it also helps prevent ignition or flames caused by shock or internal pressure.

Today’s cars have the fuel filler cap installed over the gas cap, also known as the “Gaso tank cap”. But cars that don’t have fuel filler covers are very likely to face fuel theft or vandalism.

Locking System

The locking system is the main factor that relies heavily on the fuel tank cap. The locking mechanism must be smooth enough to be easy to operate when locking and unlocking.

Also, make sure it has an auto-locking system – which automatically locks the lid when you put it in the gas tank. When locking the lid, it should make a “clicking sound” when it fits into the fuel tank. Currently, the cap has valves at the corners to provide a perfect fit.

Quality Products

Locking gas caps must be manufactured by the OEM as they offer high-quality materials while maintaining high security. If possible, check whether it is made of coarse plastic or not. Sturdy plastic is a high-quality hard plastic that will not easily break or leak.
