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.

Features:

• VpCI-326 provides universal corrosion protection to ferrous and non-ferrous metals
• VpCI-326 is nitrite-free, non-toxic, and thermally stable, providing long-lasting contact and vapor phase corrosion protection
• With VpCI-326, most lubricants can be upgraded in their anti-corrosion ability providing continuous corrosion protection during operation, standby, and shutdown periods
• Passes through 1 micron filter
• Conforms to MIL-PRF-46002C
• Conforms to MIL-I-85062 (Additives to oils)
• Conforms to MIL PRF-16173E
• NATO 6850-66-132-6100
• NSN 6850-01-470-3358
