Product Overview
PTFE packing is woven from PTFE fibers and classified as a gland‑packing seal. It is installed in the stuffing boxes of pumps, valves, and agitators to provide rotary, reciprocating, and static sealing for shafts. It exhibits excellent resistance to most highly corrosive media, has a low coefficient of friction, does not contaminate the process fluid, and is widely used in chemical, pharmaceutical, and food‑processing industries for corrosion‑resistant sealing applications.
Application areas
Chemical industry: centrifugal pumps, reactor agitator shafts, valve stems; seals for media containing strong acids, strong bases, organic solvents, and oxidizing agents.
Food and Pharmaceutical Industries: pharmaceutical equipment, food-grade transfer pumps, hygienic non-leaching seals
Papermaking and Synthetic Fiber: Corrosive Pulp, Chemical and Pharmaceutical Liquid Pump Valves
Electroplating Environmental Protection: Pickling Tank, Anti-Corrosion Circulation Pump
Fine chemicals, high-purity fluid equipment for semiconductors
Product Advantages
Exceptionally resistant to corrosion; compatible with the vast majority of acidic and alkaline solvents.
Excellent self-lubricating performance, low coefficient of friction, and resistant to shaft and sleeve scuffing.
Clean and hygienic; the oil-free white PTFE does not contaminate materials and is suitable for food and pharmaceutical applications.
Resistant to both high and low temperatures—does not become brittle at low temperatures nor carbonize at high temperatures. Easy to disassemble and assemble; the packing gland is directly filled, making maintenance and replacement straightforward.
Fully equipped, source factory
FAQ
Can I take a sample for testing?
Yes, samples can be sent for testing before placing a bulk order.
Do you have a pre-shipment inspection procedure?
Yes, we always test the product before delivery.
Can I have my own custom-made product?
Yes. We can provide OEM and ODM services, including design, logos, packaging, and more.
What’s the difference between CBN grinding wheels and diamond grinding wheels?
CBN (cubic boron nitride) is suitable for grinding high-hardness alloy steels;
Diamond grinding wheels are suitable for grinding brittle materials such as cemented carbides and ceramics.
