Steel Drum Closures 2" and 3/4"
Bung Closures for Closed Head Steel Drums
What This Product Is
Steel and stainless steel drum closures in 2 inch and 3/4 inch, fitted with EPDM, BUNA or PE gaskets and finished in CR3, CR6 or lacquer. They are the standard bung set for closed head steel drums, barrels and metal cans, and are opened and closed with a drum wrench.
Key Benefits
- Three gasket materials let the seal be matched to the filled product
- CR3, CR6 or lacquered finishes protect the closure through storage and transit
- Cold rolled or stainless steel bodies survive repeated opening and reuse
- Standard 2 inch and 3/4 inch sizes fit the usual closed head drum flange pair
What Goes Wrong Without It
- A worn or mismatched bung gasket is the most common leak path on a steel drum
- Regulated shipments are refused when closures do not meet transport requirements
- Bare steel closures corrode in storage and seize into the drum flange
Application Scenarios
- Steel drum reconditioners replacing closures on returned drums
- Lubricant and chemical fillers packing in closed head steel drums
- Drum manufacturers specifying closures to match their flange type

How to Specify and Use It
Match the closure size to the drum flange, normally 2 inch plus 3/4 inch
Select the gasket material against the product being filled
Tighten with a drum wrench to the drum maker's torque rather than by hand
Inspect the gasket at every reuse and replace it if compressed or hardened
Comparison With Other Products
Steel closures are crimped and wrenched into a metal drum flange and suit solvents, lubricants and heat. Plastic drum closures in the same range are for plastic drum necks, are lighter and cheaper, and cannot be used in a steel flange.
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.
