Drum Cap Seals 2" and 3/4"
Tinplate and Aluminium Seals for 2 Inch and 3/4 Inch Bungs



What This Product Is
A metal drum cap seal in 2 inch and 3/4 inch, made from tinplate or aluminium at 0.22 to 0.32mm thickness and finished in white, red or a customised colour. It is crimped over a drum closure to give a tamper-proof and waterproof cover that can also carry a printed logo.
Key Benefits
- Tinplate or aluminium resists corrosion in harsh storage and transport conditions
- 0.22 to 0.32mm gauge crimps cleanly without tearing or springing back
- Colour choice and printed logos turn the seal into a product code and a brand mark
- Two sizes match the 2 inch and 3/4 inch closures on a standard drum
What Goes Wrong Without It
- A closure on its own leaves no evidence if a drum is opened in the supply chain
- Water and dirt collect in the closure recess and work into the thread
- Unbranded drums arriving at a customer site are hard to identify at a glance
Application Scenarios
- Paint, chemical, oil and lubricant fillers sealing outbound drums
- Exporters shipping through several handling points
- Brands that use the seal face as a printed identification panel

How to Specify and Use It
Fit and torque the drum closure first
Place the matching 2 inch or 3/4 inch seal over the closure
Crimp with a drum cap seal crimping tool rather than pressing by hand
Confirm the seal cannot be turned before the drum leaves the line
Comparison With Other Products
The metal cap seal is specified where drums are steel or where the seal must carry printing. The PE plastic drum cap seal in 77mm to 87mm is the equivalent for plastic drum closures and is fitted without a tool.
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.

United Packaging operates a professional quality control system under ISO 9001 certification, following quality management procedures intended to minimise the risk of defects.
