VpCI®-326 is a corrosion inhibitor oil additive for hydraulic oil and gearbox assemblies. It performs effectively under adverse conditions and in the presence of such corrosive species as chlorides, sulfur compounds, or hydrogen sulfide.

 VpCI®-326 contains no hazardous chromates, nitrites, or phosphate inhibitors.

 With VpCI®-326, most lubricants can be upgraded in their anti-corrosion ability providing continuous corrosion protection during standby and shutdown periods.
