Castrol Brayco 300 Lubricating Oil, General Purpose, Preservative

DESCRIPTION

Castrol Brayco 300 is a blend of highly refined petroleum oil with suitable additives which provide corrosion prevention, oxidation resistance, and freedom from galvanic corrosion in brass-steel bimetallic systems. The viscosity is similar to a light machine oil. Brayco 300 is a water-displacing oil for general-purpose applications at low and medium temperatures (-70ºF to 300ºF).

APPLICATIONS

Castrol Brayco 300 is designed for the lubrication and preservation of small arms, automatic weapons, and fuse mechanism applications, especially where a low-temperature, water-displaced oil is desired. It may be used to protect unpainted metal surfaces from the effects of indoor storage for periods of three to six months, after which it remains readily removable.

Brayco 300 will also protect magnesium and aluminium against corrosion at low and medium temperatures (-70°F to 300°F). Brayco 300 may be applied by brush, dip, swab, spray, or squirt can. Depending on the method of application and surface geometries, Brayco 300 will cover 1,000 to 3,000 square feet per gallon. For water displacement, it may be applied by these same methods. Displaced water should be removed from dip tanks at suitable intervals.
