Top Gas should only be used in Gas guns indicated as such on the products pages. Using Top Gas or more powerful gases in a gun rated for HFC134a may cause permanent damage. Please take note that Top Gas will generate higher power and stronger blowback, but may cause damage in guns that are not designed to withstand the higher pressure.
As such, you should check the specification of your gas gun on our site to see whether it is suited to using Top Gas. If you are unsure and want to be safe, choose HFC134a gas.
