Abstract
An improved hydrometer collar for use within lead-acid storage batteries of the type installed within vehicles includes a cylindrically-shaped member having an annular side wall. A plurality of sealing rings are formed upon the outer surface of the annular side wall. Each one of the plurality of sealing rings is spaced axially apart from each other in a substantially parallel relationship so as to form annular grooves therebetween. A small wiping rib is formed integrally with each one of the plurality of sealing rings and extends radially outwardly therefrom. Each one of the wiping ribs is disposed substantially intermediate an upper surface and a lower surface of a corresponding one of the plurality of sealing rings. The wiping ribs are easily deformable so as to fill any imperfections existing upon the interior surface of a battery casing bore of the storage battery into which the collar is inserted thereby creating a fluid-tight seal therewith.
