Carsten Holms CH NF2 is braided from selected, long fibre, heavy duty, flax yarns thoroughly impregnated yarn by yarn with PTFE and treated with break-in lubricants. The packing is designed to give a very low coefficient of friction, resistance to wear and rotting, good compressibility, high flexibility, high tensile strength and comparative ease of installation and take-up especially on large cross-sections.
CH NF2 PTFE flax packing is especially designed to seal large cross-sectional areas and is ideal to solve the extracting sealing requirements of stern glands in the marine field. The packing will also be of superior service in heavy reciprocating machinery, rotary applications handling abrasive media and heavy duty static applications such as tank lid seals.
