FDA PTFE Gasket — Material Specifications, Engineering Data & OEM Supply
FDA PTFE Gasket by HEMSUN is manufactured in Gujarat, India, delivering high-reliability performance in aggressive fluid handling and chemical environments. Formulated from premium PTFE fluoropolymer to provide low friction, high dielectric strength, and precise drawing tolerances.
Where FDA PTFE Gasket is used
Static face seal between flanges, compressed to fill surface irregularities and hold a joint tight through thermal cycling.
Specified where FDA 21 CFR 177.1550 listed resin is required for direct food, dairy and beverage contact, with cleanability and no taste transfer.
Common in dairy, brewing, edible-oil and bottling lines, and on filling equipment that is washed down between batches.

Manufacturing process
Our dedicated manufacturing cells produce FDA PTFE Gasket from premium PTFE fluoropolymer powder stock. After uniaxial preforming in precision tooling, components undergo computer-monitored sintering cycles and diamond-tooled CNC profiling to hold exact drawing dimensions.
Material selection notes
Featuring FDA-compliant virgin PTFE fluoropolymer or specialized filled compounds, FDA PTFE Gasket provides reliable sealing and low-friction motion under continuous operating temperatures up to +260°C. Filler additions enhance mechanical rigidity, wear resistance, and thermal conductivity for heavy mechanical loads.
How to specify your order
To evaluate FDA PTFE Gasket for your project, submit component PDF drawings and resin requirements. HEMSUN engineers review part geometry, recommend appropriate compression tooling or CNC machining approaches, and provide competitive commercial proposals.
Quality checks and inspection
Quality assurance for FDA PTFE Gasket includes 100% optical dimensional inspection, digital micrometer verification, CMM coordinate layout testing, and water displacement specific gravity checks according to ASTM D792. High-voltage spark testing up to 80 kV/mm verifies absence of internal pinholes and voids.
