Buying Guide
What drum sizes and bung types do I need to support?
Most aluminum bung wrenches cover 2″ and 3/4″ bung caps across 10–55 gallon drums. Confirm your drums use tight-head heads and standard bung sizes before purchasing.
Is non-sparking or spark-free operation important for my work?
Yes for environments with fuels, oils, solvents, or flammable contents. Non-sparking aluminum reduces ignition risks and supports safer handling.
