National Fluoromers is a prominent manufacturer, supplier, and exporter of PTFE valve seats and components, engineered to deliver reliable, leak-proof sealing and smooth operation in a wide range of valves used across industries. Designed for high chemical resistance, low torque performance, and temperature stability, our PTFE valve components are ideal for aggressive media and high-cycle environments.

Whether for ball valves, butterfly valves, diaphragm valves, or custom valve assemblies, our precision-machined PTFE parts ensure tight shut-off, reduced maintenance, and long service life.

what are PTFE valve seats & components?

PTFE valve seats are circular or contoured inserts that form a sealing interface between the valve body and the moving element (such as a ball or disc). PTFE valve components include seals, guides, diaphragms, spacers, and linings—machined or molded to fit specific valve geometries.

Thanks to PTFE's inherent chemical resistance and self-lubricating properties, these components are ideal for preventing leakage, corrosion, and product contamination in high-demand applications.

key features
  • Excellent chemical compatibility: Unaffected by aggressive acids, bases, solvents, and gases.
  • Thermal resistance: Operational from –200°C to +260°C.
  • Non-stick surface: Reduces torque, prevents fouling and scaling.
  • Low coefficient of friction: Enables smooth operation and minimal wear.
  • FDA & USP compliant grades available: Suitable for food, pharmaceutical, and biotech valves.
  • High dimensional accuracy: CNC machining ensures perfect fit and finish.
