The plastic drum seals are polypropylene made cap seal, designed to lock directly onto plastic bung on HDPE drum barrels under specification guidance. These two combined to be the basic cap system for tight head poly drum, either with 2'' and 3/4'' NPT openings or with 2'' NPT and 2'' buttress openings.
Same as other types of drum cap seal, the plastic drum seals protect the filling content from contamination and pilferage.
The snap on style expresses the application convenience to the users. These plastic drum seals are a more easily operated type than metal cap seals. They are tool free to cover and remove such plastic drum seals.
There are red, blue and white under selection. General type of distinguishable red color seals can alert the drum owner once the cap is opened or removed. There is a potential change in the filling content.
