VpCI-326 is a corrosion inhibitor oil additive for hydraulic oil and gearbox assemblies. VpCI-326 performs effectively under the adverse conditions of 100% relative humidity, 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. VpCI-326 utilizes the finest paraffinic petroleum distillates as carriers. VpCI-326 possesses an exceedingly high flash point, enhancing in-plant safety when compared to common oil protectants. VpCI-326 is supplied in concentrate form, which is easily diluted with lubricating, hydraulic or preservative oils, saving shipping and inventory expense. VpCI-326 is a broad range corrosion inhibitor not only effective on ferrous metals, but also effective on zinc, aluminum, galvanized steel, copper, cadmium, silver, brass and many other alloys.

Conforms to MIL P-46002B, MIL I-85062, MIL C-16173D (Grade 3), and MIL I-85062.
