P.T.F.E Packing with Inblend Graphited LubricantAdvantages : Adequate lubrication for low friction runs. No embrittlement.Graphite in Inblend controls the thermal expansion of P.T.F.E by 20%, thus eliminating any jamming, overheating or extrusion.Undeterred heat dissipation for cooler shaft runs without wear. Typical Applications :Steam dryers, water pumps, agitators. Steam / Gas valves. Chemical pumps & valves.
