The fine wire mesh screen in the outlet of safety gas cans is known as what?

The fine wire mesh screen in the outlet of safety gas cans is referred to as a flash arrestor. This component serves a crucial function in preventing flames or sparks from entering the gas can, which could ignite the flammable vapors inside. By allowing gases to escape while preventing flames from entering, the flash arrestor enhances safety when transferring or storing flammable liquids.

The design of the flash arrestor minimizes the risk of fire hazards by acting as a barrier and ensuring that only vapors can exit, thus reducing the possibility of ignition. This is essential for safety in environments where flammable materials are present, making it a vital feature of safety gas cans.
