Parker’s O-Lube is an outstanding general purpose grease lubricant. The barium base petroleum grease lubricant prolongs the life of synthetic rubber seals. It offers excellent surface adherence and lubrication with inherent water resistance. It is recommended for low-pressure pneumatic systems, as well as reciprocating and low-speed oscillating or rotary applications. Parker O-Lube works well in a -20°F to 180°F temperature range.
