Custom PTFE Gaskets & Sealing Washers | Precision Fluoropolymer Seals

Product Overview & Customization Options

PTFE (Polytetrafluoroethylene) gaskets and sealing rings provide exceptional sealing performance under challenging operating conditions. Whether you require standard pipe flange gaskets, high-thickness seals, or custom dimensions made to your specific CAD drawings, we provide complete OEM manufacturing services.

From thin flat washers to heavy-duty thick rings, every part is manufactured to ensure exact outer diameters, inner diameters, and uniform thickness with clean, burr-free edges.

Key Product Features & Benefits

• Wide Range of Sizes & Thicknesses: Custom thickness profiles ranging from thin gaskets up to extra-thick ring seals to match your pressure and flange sealing requirements.

• Complete Chemical Resistance: Unaffected by aggressive acids, alkalis, corrosive solvents, and reactive fluids across the entire pH range from 0 to 14.

• Broad Temperature Range: Maintains stable sealing integrity and material flexibility from low cryogenic conditions (-180°C) up to high operating temperatures (+260°C).

• Low Friction & Non-Stick: Excellent non-stick surface prevents sticking to flange faces, making equipment disassembling and maintenance easy during servicing.

• High Density & Smooth Finish: Precision lathe cutting ensures high dimensional accuracy, flat sealing faces, and zero porosity.

Technical Capabilities & Custom Parameters

• Product Types: Standard flat gaskets, raised face gaskets, thick valve seals, custom washers, flange rings, and stepped sealing rings.

• Processing Methods: Precision automatic lathe turning, CNC machining, cutting, and compression molding.

• Dimensional Accuracy: Outer diameter, inner diameter, and thickness controlled strictly according to client drawings or specifications.

• Material Options: 100% Virgin PTFE for maximum purity and chemical purity, or filled PTFE grades (glass fiber, bronze, carbon, or graphite) for enhanced wear resistance and reduced creep under load.

Primary Applications

• Chemical Processing: Flange connections, reactive liquid pipelines, acid handling systems, and storage tank seals.

• Pumps & Valves: Valve stem packing, pump body seals, bonnet gaskets, and dynamic sealing rings.

• Pharmaceutical & Food Industry: Sanitary flange gaskets, dosing equipment seals, and filling machine components requiring non-contaminating materials.

• General Industrial Piping: High-temperature steam lines, hydraulic system seals, and general flange connections.

Quality Control & Packaging

• 100% Dimensional Inspection: All key dimensions including inner diameter, outer diameter, and thickness are checked with precision digital calipers before shipment.

• Clean & Secure Packaging: Gaskets are stacked and wrapped in protective film or packed in barrels to preserve surface cleanliness, prevent deformation during transport, and ensure rapid inventory organization.
