Steel Plug Plated & Steel Plug Lined

Tri-Sure® offers a full range of plated and lined drum bungs and steel flanges which are produced to ISO 228 G34 and G2 standard metal packaging dimensions.

All Tri-Sure® G2 drum bungs are produced with the patented R-Plug design. R-Plug is a retaining ring system that assists in keeping the gasket in place when the plug is threaded into the flange, lowering the opportunity for looping, and when it is unthreaded from the flange, hampering gasket sticking. Keeping the washer in place during threading also allows the plug to torque to the recommended value required for functionally, providing for maximum gasket compression to help prevent plug back-off during storage and transit.

Tri-Sure® provides drum bungs and steel flanges in three plating styles: zinc-chromate; iron-phosphate, and tin plated. Zinc-chromate plating makes use of sustainable and environmentally-friendly Chromium 3 passivation.

Lined closures provide specific chemical resistance for hard-to-hold products. Lined drum bungs and steel flanges are available with a complete family of phenolic and epoxy-phenolic linings that are produced using the industry leading Tri-Sure® RDL lacquer system:

Epoxy-Phenolic

RDL 16 – Gold tint

RDL 06 – Red oxide

RDL 39 – Tan

RDL 29 – Clear

RDL 50 – Olive Green

RDL 44 - Buff
