Daubert Cromwell VCI wire protects metal tubing, pipes, cylinders and hard-to-reach areas. The blue LDPE wire, 1/8" diameter provides superior multi-metal corrosion protection. To use, cut a piece of wire the length of the cylinder or tube. The VCI vapors will fill the space, protecting the metal with an invisible layer of corrosion inhibitor chemistry. Parts stay clean, dry, and corrosion-free for up to 24 months. Ideal for stored parts and export shipments. Available in rolls and cut-to-length pieces.
