English
Expanded PTFE Valve Stem Packing is made from 100% white pure virgin PTFE resin. It is a white, soft and round product. In possession of the characteristics of high tensile strength, self-lubrication, low coefficient of friction and corrosion resistance, it can be widely used in valves, faucet stems, rotating shafts, reciprocating plungers, stuffing boxes and flanges etc.
Advantage:
• Easy installation,cheap cost.
• High temperature resistance, long service life.
• Ideal for valves, faucet stems, rotating shafts
• No pollution for fluid.
• Chemical corrosion resistance.
• Excellent flexibility,few cold flow deformation.
• Clean, from dust-free workshop.
