Grades and Applications


Virgin PTFE for packing, seals, and bushings


25% fiberglass-filled grade for common seals and bushings

1911 and 1921

Carbon/graphite-filled grades for bearings, piston rings, rider rings and various seals. An excellent combination that provides good service life. 1911 has 25% fill; 1921 has 35% fill.


50% stainless steel-filled grade for bearings and valve seat applications where high load and corrosion are the main concerns.


55% bronze/5% moly filled filled grade for bearing and seal applications where high load strength is needed.


Ceramic-filled grade (25% mica) for applications where high wear resistance is required.


35% carbon fiber-filled grade where high strength and high wear performance is required: a high-performance composite grade.
