National Fluoromers is a trusted manufacturer, supplier, and exporter of PTFE ready-cut gaskets, offering precision-cut sealing solutions for demanding chemical, food, pharmaceutical, and high-temperature environments. These gaskets are CNC or die-cut from high-quality PTFE sheets to match customer drawings, standard flange profiles, or special equipment shapes.

Designed for aggressive media, PTFE gaskets provide long-term sealing reliability, non-stick performance, and resistance to nearly all corrosive substances.

what is a PTFE ready-cut gasket?

A PTFE ready-cut gasket is a flat, ring-shaped or custom-profile sealing element made from polytetrafluoroethylene. These gaskets are cut to precise dimensions using CNC machines or die punches to fit between two mating surfaces—typically pipe flanges or equipment interfaces. Their purpose is to prevent leakage of gases, liquids, or powders in challenging conditions.

Due to PTFE’s chemical inertness and temperature resistance, these gaskets are ideal for static sealing in harsh environments where elastomers would degrade.

key features
  • Chemical resistance: Inert to nearly all acids, solvents, and reactive media.
  • High temperature stability: Works from –200°C to +260°C.
  • Non-stick & non-contaminating: No product build-up or adhesion.
  • Custom-cut for precision fit: CNC machined or die-cut to exact requirements.
  • FDA & USP grade available: Suitable for food, pharmaceutical, and cleanroom use.
  • Low compressibility set: Maintains sealing pressure over long durations.
