Daubert Cromwell's Bore Tube Packing Protects Metal from Corrosion

Daubert Cromwell has expanded its selection of anti-corrosion packaging for military and industrial commercial uses with a VCI-treated bore tube that protects barrels, spares, shafts and cylindrical shapes. The spirally wound bore tube is constructed with the company’s VCI (volatile corrosion inhibitor) paper, which is qualified to Mil-PRF-3420. The VCI tubes, most popular in 19" lengths, are designed to prevent rust inside firearms, hollow tubing, piping, and hard-to-reach narrow spaces.

Each Nox-Rust VCI bore tube provides safe, non-toxic rust protection to steel, cast iron and ferrous alloy surfaces. The protection is dry and clean and is said to eliminate the need to apply oils or liquids. When the tubing is removed, the part is ready to use without need for further cleaning or rework. Tubes are fully recyclable and repulpable. 

The bore tube is placed into the length of a clean, dry cylinder shape up to 1" in diameter. Both ends are then closed off to maintain packaging environment. The corrosion protection is said to last as long as 24 months in proper storage conditions.

For metal parts of ferrous/non-ferrous combinations, the company also offers Premium Metal-Guard VCI film for added barrier protection.
