AMSOIL Synthetic Multi-Purpose Grease (GLB)

AMSOIL Synthetic Multi-Purpose Grease, NLGI #1 (GLB) Synthetic Multi-Purpose Grease, NLGI #1 (GLB)

AMSOIL Synthetic Multi-Purpose Greases are qualified against the highest grease standards and are designed for multiple use applications. Composed of premium quality synthetic base oils and lithium complex thickeners, Multi-Purpose Greases provide superior film strength, shear resistance, adhesion properties and mechanical stability, and they excel in temperature extremes by providing excellent oxidation stability, high temperature dropping points and low temperature torque values and pumping capabilities. AMSOIL Synthetic Multi-Purpose Greases are formulated with oil soluble extreme-pressure additives for heavy loads, as well as oxidation and corrosion inhibitors that impart good oxidation stability and rust protection.

Performance Features

  • High dropping point of 500°F+
  • Resists thermal and oxidation degradation
  • Excellent water-washout resistance
  • Good low temperature pumpability and torque values
  • Adhesive and shear stable to prevent squeeze out

Applications or Requirements

  • GLB (#1) ASTM D-4950 (NLGI) Service GC/LB
  • GLB (#1) Cincinnati Milicron P-72 Spec

Application Recommendation

AMSOIL Synthetic Multi-Purpose Grease grade #1 is recommended in manual or automatic lubricating systems. NLGI #1 (GLB) has better mobility and is the preferred choice for colder applications, automatic lubrication systems with long pumping runs and gear box applications (where recommended by manufacturer).

The correct consistency grade of AMSOIL Heavy Duty EP Grease is recommended for use in heavy and light duty applications found in manufacturing plants, automotive applications, agricultural equipment and construction equipment. These include, but are not limited to, roller bearings, plain bearings, gears, bushings, wheel bearings, chassis lubrication, universal joints, ball joints, tie-rod ends, steering knuckles, and heavily loaded pivot pins on mining and off road equipment such as power shovels, draglines, wheel and back hoe loaders, excavators and bulldozers. AMSOIL Heavy Duty EP Greases are suitable for use up to 325° F. When operating at elevated temperatures, frequent regreasing may be required.

AMSOIL GL Lithium Complex Greases are compatible with many other types of grease. However, it is recommended that when changing greases, the equipment be cleaned of the old grease when possible or flushed with a liberal amount of the GL Grease while the mechanism is in operation. Closely monitor the system for any inconsistencies. Any grease compatibility questions should be referred to your AMSOIL representative or AMSOIL INC.

Application Maintenance

Maintaining a clean work environment is important when equipment greasing is performed. Wipe grease fittings clean prior to injecting grease to prevent contaminant ingestion. Maintain bearing housings one-third to one-half full of grease. Do not over-grease as excessive heat buildup can result. Supplement standard grease maintenance by periodically cleaning and packing housings with fresh grease on an established maintenance schedule.

AMSOIL GLB Series Greases are available in 14-oz. cartridges, 35-lb. pails, 120-lb. kegs and 400-lb. drums. AMSOIL Industrial Lubricants are stocked in Superior, Wisconsin and in select regional distribution centers throughout the United States and Canada. AMSOIL will stock additional quantities of lubricants or special order products based on customer requests and regional demands.
