ABSTRACT:
A vent plug includes a thermophastic tubular body for insertion in an aperture in the lid of a battery. The vent plug has at its upper end an integral lid with a gas venting aperture formed therein. A removable insert is secured within the tubular body and defines a tortuous gas venting path. The insert and the body are constructed to define a space with which the gas venting aperture and the gas venting path communicate, the space accommodating a porous flame retarding body.
