teflon ball

We are proud to introduce our new family of Teflon balls. This product offers a solution to valve leaks in even the harshest environments. Its’ waterproof, non-porous surface can be machined or molded to any desired size. 

Benefits of Teflon Balls

 Teflon is inert, chemically resistant, and has a wide operating temperature range. Teflon balls are corrosion-resistant against caustic chemicals. Our Teflon balls have a long surface life and excellent ductility, making them excellent seals. 

Materials Used for PTFE Balls

There are different materials used for Teflon balls

  • Virgin Grade PTFE
  • Teflon NXT 85 Modified PTFE
  • Stainless steel-filled PTFE (50% 316 stainless steel 50% PTFE)
  • 25% Glass-filled PTFE
  • 15% Glass-filled PTFE
  • 10% Carbon 10% Glass-filled PTFE
  • Bronze

Teflon Ball Uses

Teflon balls are found in various industrial applications. Commonly, Teflon balls are found in

  • Ball Valves
  • Check Valves
  • Compressors
  • Bearings
  • Gears
  • Slide plates
  • Volume displacement

Because of the purity of the PTFE balls, they are often found in medical devices, food preparation, electronic, pharmaceutical, and industrial applications.
