NEO Synthetics HPCC Number 1 Grease, 100% synthetic high performance Calcium complex. NEO HPCC Number 1 grease is specialty grease for linear and oscillating mechanisms and couplings, such as constant velocity couplings (CV joints) and sealed bearings.

It will take heavy shock loads, frequent axial movements, large speed variations and frequent reversing. It is made with a higher molecular weight synthetic base stock and will withstand extreme temperatures. It has a very strong resistance to water washout in rain or even salt water.

NEO HPCC Number 1 Grease is designed for low oil separation under centrifuging. It is classified as an NLGI 1 1/2 Grade grease but will react to the amount of shear loading and will stiffen to a hard number 2 grade grease.

The grease is designed to skin over to create a shell that resists dirt and moisture, but this shell does not in any way detract from the lubricating qualities. For this reason, this is an excellent product for sealed for life bearings or large open gears. It is equally at home in dusty climates and very wet locations.


NEO HPCC Number 1 has been used for selected applications as found on demanding Military Mobile Equipment, All-Terrain Vehicles, Armored Troop Carriers and Commercial Off-Road Construction equipment. HPCC Number 1 can be used on sensitive metallurgy including copper, silver, tin, aluminum and their alloys.

It's exceptionally resistant to water wash conditions including emulsions. HPCC Number 1 is specially formulated to slightly skin dry when in contact with air to provide self-sealing protection when seals are deteriorated. Special compounding and lubricating solids provide superior anti-seize characteristics and exceptional acid and corrosion resistance.

Special applications:

Anti-seize properties upto 1200°F, recommended as an assembly and spline lubricant, cam lubricant, jack screws and fasteners, logging hammers, knuckle joints, outboard bearings and launch grease, as well as pump and valve lubrication in moderately hot, corrosive and wet environments.


NEO High Performance Calcium Complex (HPCC#1) Number 1 Grease is classified as NLGI Grade 1 1/2 and will Grade 2. Color is Moly Gray. Subject to normal manufacturing tolerances.
