Product Description: TENA-FILM EXTREME PRESSURE INDUSTRIAL OILS are high gravity oils of 100% paraffin extraction dewaxed in the refining process to prevent gumming. In the refining stage, only the better molecules of natural paraffin crude are salvaged, leaving a well-balanced, stable chain of molecules that imparts the very maximum amount of anti-wear properties, with much greater lubricity and film strength per grade than other E.P. petroleum oils. TENA-FILM EXTREME PRESSURE OILS are therefore more versatile in application.
