Safety fill vents and funnels fit the 2 in (51-mm) bung on a vertically-stored drum. The brass vent provides automatic pressure and vacuum relief and includes a brass cap with safety chain tethered to the vent to prevent misplacement or loss. Remove cap during drum filling operations. Model no. 08211 includes a 9-in(229-mm) wide polyethylene funnel to facilitate solvent waste disposal and reduce spillage. Keep vent capped in closed position after filling operations to prevent flammable vapor from escaping. Six in (152-mm) flame arrester safely dissipates heat and prevents flashback from external ignition sources.
