Expander Lube - Type B
Series 114 Expanders
Wilson Expander Lube is a water-soluble lubricant especially compounded for use with tube expanders. When rolling large or small, ferrous or nonferrous tubes, use Wilson Expander Lube for smoother rolling and longer expander life. For clean tube ends after rolling, simply wash with water. Wilson Expander Lube is used straight from the can without dilution.
