Our robust cast iron Drum tap has a 2-inch BSP thread suitable for dispensing liquids from our 225kg drums of resins and gelcoats. Due to its wide opening it can easily cope with viscous liquids such as gelcoat. As there are no plastic or rubber seal components these taps can be easily washed in solvents such as acetone.
One handy tip is to wash the tap between uses and by applying a mould release wax on the sliding surfaces of the tap after each clean, this can prevent it from seizing due to congealed or dried resins/ gelcoats, this will also prolong the life of the tap.
However, avoid using oils or grease which may risk contamination of your resins and gelcoats.
