Chesterton 725 Nickel Anti-Seize Compound

Overview

Chesterton 725(E) Nickel Anti-Seize Compound is an assembly lubricant combining the extreme pressure, corrosion resistant anti-seize abilities of colloidal nickel, aluminium and graphite in an oil suspension which will withstand temperatures up to 1425°C (2600°F). The product seals and protects metal parts under extreme conditions by providing an ultra-thin coating of nickel particles. The particles form an antifriction barrier that will not burn, wash or scrape off, preventing pitting from the galvanic action between dissimilar metals that could occur if the metals were not separated. It has a balanced coefficient of friction, so threads are not stretched and more accurate load values are possible during assembly, and it saves threads and parts for reuse by preventing galling damage and breakage during opening. It will not wash off in either fresh or salt water, and can be used indoors, outdoors and in marine applications. Meets MIL-A-907D and is NSF H2 registered.
