Diagonally braided from Preox yarn, impregnated throughout with pure graphite powder and a corrosion inhibitor. Please note: the colour of the actual product might vary from the image on this data-sheet.
Style AF 3012 is an economic solution for applications above the temperature limit of PTFE and gPTFE packings. It fills the gap between the "medium temperature" packings for up to 280°C and the more expensive "high temperature" packings made from pure carbon or graphite. Preox yarn has a low coefficient of friction and excellent heat transmitting properties.
Economic multi-purpose packing for elevated temperatures. The dense, yet flexible packing assures excellent contact with the shaft or spindle and good gland load transfer.
Application: Can be used in pumps, sliders, stirring equipment, refiners and valves in many different industries. Also suitable for boiler feed pumps.
User: SPIRALIT AF 3012 is suitable for use with most chemicals, diluted acids and lyes, water, steam, oil, solvents, brine, sewage, etc.
