PTFE packing is a pure PTFE fiber yarn braided into square cross section. High cross-sectional density and structural strength. Low confident

of friction result in easy shaft running. and "Black teflon"can be used at dynamic sealing location under with pressure. ptfe packing can used in general sealing performance. It is designed for all the chemical compounds (excepting cast alkaline metals and the gaseous fluorine),

alternative and rotary motions shafts operating at low peripheral speed,rod ,pistons,valves steams,expansion joints,however high purity and corrosion resistance is required, such as food industries, pharmaceutical factories, paper mills and chemical fiber plants etc.

 

They are universal packings suitable for valves, pumps and agitators in most mediums.

 

BKP1101a Pure PTFE packing

It is soft, mainly used in static sealing application.

 

 

BKP1101b Pure PTFE packing with oil

It is treated with special silicon lubrication. Main designed for dynamic sealing application.
