Kaxite's PTFE Special Sealing Ring for Filter Plant is a custom-machined seal made from virgin or filled PTFE (glass fiber, carbon, graphite, bronze), operating from -200°C to 260°C and up to 10 MPa, with diameters from 10 mm to 1,500 mm. It is used in chemical, food, pharmaceutical, and water filtration plants, and is ISO 9001:2015 certified with full EN 10204 3.1 material traceability. Factory-direct pricing and free samples are available. Request a quote →
It is used to seal filter housings, filter plates, and piping connections, preventing leakage of liquids or gases under chemical, thermal, and pressure stress.
Standard PTFE seals operate from -200°C to 260°C. Filled PTFE grades can extend performance depending on the filler.
Yes. We machine custom diameters from 10 mm to 1,500 mm and offer virgin PTFE or filled PTFE (glass fiber, carbon, graphite, bronze).
Samples: 7–15 days. Bulk orders: 15–25 days. Expedited service available.
Kaxite's PTFE Special Sealing Ring is specifically engineered for filter plant applications where chemical resistance and sealing reliability are critical. Filter plants operate under aggressive conditions — corrosive media, temperature fluctuations, and continuous pressure cycling. A standard seal fails quickly in these environments. Our PTFE sealing rings are machined from virgin PTFE or filled PTFE compounds to match your specific media, temperature, and pressure requirements.
PTFE is inert to almost all industrial chemicals, including strong acids, alkalis, solvents, and oxidants. It operates continuously from -200°C to 260°C and has the lowest coefficient of friction among industrial sealing materials. For filter plant applications, we select the appropriate PTFE filler — glass fiber for chemical resistance, carbon/graphite for wear resistance, or bronze for high-pressure extrusion resistance — based on your operating conditions.
