What are Teflon-Coated Flat Washers?

A flat washer is a thin, round plate with a hole in the middle, used with bolts, nuts, and screws to distribute load, prevent surface damage, and reduce vibration.

When coated with PTFE (Teflon), flat washers gain enhanced properties such as:

Superior corrosion resistance
Low friction surface to prevent seizing and galling
Thermal stability for high/low temperature conditions
Non-stick and insulating surface for electrical and hygienic applications

This makes Teflon-coated washers ideal for oil & gas, petrochemical, marine, power, and chemical industries.

Key Features & Benefits of Teflon-Coated Washers

✅ Excellent Chemical Resistance – Withstands acids, alkalis, solvents, and aggressive fluids
✅ Low Coefficient of Friction – Ensures smooth assembly/disassembly and longer fastener life
✅ High Thermal Stability – Performs under extreme hot and cold conditions
✅ Anti-Seizing & Non-Stick – Prevents galling between bolts, nuts, and washers
✅ Corrosion Protection – Extends fastener service life in harsh environments
✅ Electrical Insulation – Suitable for power, transformer, and electronic applications
