Plastic Bungs can be used for a variety of drum types; i.e. steel drums with octagonal-base openings, plastic and steel drums with circular-base openings, and fiber drums.
Polyethylene plugs are high-density, natural in color, and are self-gasketing (no extra gasket required). Nylon Plugs are great for petroleum products; gasket is required.
Standard sizes available are 2" and 3/4" plugs.
