PTFE Gaskets - Pumps, Valves, Piping and Fittings

PTFE gaskets are chemically resistant sealing components used on marine pumps, valves, pipe flanges and fittings. They are supplied as virgin, filled, modified or expanded PTFE designs selected for corrosive fluids, low friction and broad temperature service.

ProShipWorks provides end-to-end support to source and supply PTFE Gaskets for marine vessels, ship operators, industrial facilities, maintenance teams and procurement departments.

Standards, Certifications & Class Approval

Review the available standards and approval information relevant to the product. Actual certification, material traceability, inspection and classification requirements depend on the product type, intended application and purchasing specification.

Applicable Standards & Certification Common design and dimensional references include ASME B16.21, EN 1514-1, DIN 2690 and ASTM F104 where applicable. Chemical compatibility, pressure-temperature limits and bolt-load requirements must be confirmed from the manufacturer's current datasheet.
Class Approval Individual PTFE gasket sheets and cut gaskets do not universally carry independent marine class approval. Acceptance may be subject to DNV, ABS, Lloyd's Register, Bureau Veritas or ClassNK requirements for the installed piping or equipment system.

Installation, Maintenance & Safety Information

Installation Notes Verify gasket material compatibility, flange standard, pressure class, temperature and dimensions before installation. Clean and inspect flange faces, use the specified gasket thickness, align the gasket correctly, and tighten bolts in a calibrated cross-pattern sequence to the approved torque.
Maintenance Tips Inspect accessible flange joints for leakage, staining, bolt relaxation or damage during planned maintenance. Replace gaskets after disassembly unless the manufacturer and equipment procedure specifically permit reuse. Recheck bolt condition and torque requirements after commissioning where specified.
Safety Notes Depressurize, drain, isolate and verify zero energy before opening any joint. Use suitable PPE for the contained fluid and hot surfaces. Do not exceed the gasket manufacturer's pressure-temperature limits, and avoid excessive bolt tightening that can damage flanges or cause PTFE creep.
