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.
