b'TEF-GELTEF-GELThe function of Tef-Gel in eliminating dissimilar metal corrosion is the elimination of electrolytes from entering the interface of the metallic surfaces. Tef-Gel paste contains 40% PTFE powder and 0% volatile solvents, no silicones or petroleum solvents to evaporate, which would leave voids for electrolytes to be drawn into creating a galvanic cell. When both surfaces are coated and mated with Tef-Gel there are no voids for electrolytes (saltwater) to be drawn in by capillary action over extended periods of time.TEF-GEL 7 GRAM SYRINGE Part number: TG-.25TEF-GEL 28 GRAM SYRINGE Part number: TG-01TEF-GEL 340 GRAM CALKING GUN CARTRIDGE Part number: TG-12TEF-GEL 57 GRAM TUB Part number: TG-02TEF-GEL 454 GRAM TUB Part number: TG-16TEF-GEL BRUSH APPLICATOR Part number: TG-B16.1'
