Our Custom Filled PTFE (Polytetrafluoroethylene) Gaskets and Mechanical Seals  (DIN 28091) are engineered to provide reliable sealing performance in the most demanding industrial environments. By compounding premium virgin PTFE resin with specialized fillers (such as Bronze, Carbon, or Glass Fiber), we significantly eliminate the “cold flow” or deformation issues of standard PTFE, drastically extending the service life of your equipment.

Why Choose Our PTFE Seals?

• Superior Chemical Immunity: Virtually unaffected by aggressive acids, strong alkalis, solvents, and corrosive fluids.

• Enhanced Wear Resistance: Formulated fillings provide exceptionally low friction coefficients and improved mechanical strength under heavy loads.

• Extreme Thermal Stability: Maintains reliable elasticity and tight sealing integrity across cryogenic to high-temperature spectrums (-180℃ to +260℃).

• Zero Leakage & Low Maintenance: Precision-machined dimensions guarantee perfect flange mating, minimizing system downtime.
