Plastic Drum Closure
Bung Plugs for Plastic Barrels in Five Sizes
What This Product Is
A PE or PP closure plug for plastic drums and barrels in 70x6mm, 70x5mm, 56x4mm, 2 inch BSP and 3/4 inch BSP, with a PE, EPDM or customised O-ring. It screws into the threaded opening of a plastic barrel and is opened and closed with standard drum tools.
Key Benefits
- Five thread sizes cover the common plastic barrel openings
- PE, EPDM or a customised O-ring matches the seal to the product
- PE and PP closures are reusable across several fill cycles
- Opened and closed with standard drum tools, so no special equipment is needed
What Goes Wrong Without It
- Plastic barrels arrive with several different bung thread forms across suppliers
- Worn O-rings are the usual reason a sealed drum starts to weep
- Metal closures cannot be used in a plastic barrel thread
Application Scenarios
- Plastic drum manufacturers specifying closures at build
- Chemical and lubricant fillers packing in closed head plastic drums
- Reconditioners replacing closures on returned barrels

Comparison With Other Products
Plastic closures are for plastic barrel threads and cost less than metal. The steel drum closures in 2 inch and 3/4 inch are the equivalent parts for steel drum flanges and are specified where the drum body is metal.
Customisation
Sizes, colours and materials can be adapted where the product allows it, and branding can be applied to closures and cap seals. Confirm the change you need when you send the enquiry.
