This wrap was made for two main purposes
First: Protect the wrapper of the blue gas tank from liquids and other things when storing it, and also protect the wrapper from tampering with children and damaging it by inserting screwdrivers and other things.
Second: Protecting the user from the winding that occurs (if the valve is damaged) until it is replaced with a new valve that guarantees the safety of the user and conserves gas.
(Usually when the tire sealant head is installed on the valve that suffers from damage, the leakage will stop, but when the user needs to remove the valve head, he will suffer from pollution directly if he does not have a medicine to block the valve and stop smuggling temporarily until the valve is changed)
