PTFE Anti-Corrosion Thread Rod

PTFE Anti-Corrosion Thread Rods are engineered for aggressive environments where chemical exposure, moisture, or extreme temperatures threaten fastener integrity. These rods combine a carbon steel core (grades 8.8 to 12.9) with a polytetrafluoroethylene (PTFE) coating, creating a non-reactive barrier against acids, alkalis, and solvents. Available in diameters from M6 to M30 and lengths up to 200mm, they’re tailored for applications like chemical processing pipelines, offshore rigs, or wastewater treatment systems. The PTFE layer not only resists corrosion but also reduces friction, preventing thread galling during installation in high-salinity or acidic settings.

Base materials can be upgraded to stainless steel or alloy variants for enhanced tensile strength, while surface pre-treatments like black oxide or galvanizing add secondary protection beneath the PTFE. Electrophoretic paint or color-coded coatings (blue, red) offer visual identification for maintenance teams tracking specific systems. Customization extends to thread pitch adjustments for compatibility with existing flanges or valves, ensuring leak-proof seals in pressurized environments. Unlike standard galvanized rods, PTFE-coated variants eliminate the risk of hydrogen embrittlement in acidic conditions, making them critical for refineries, marine hardware, and pharmaceutical equipment where material failure carries operational or safety risks. Their hybrid design balances mechanical robustness with chemical inertness, offering a cost-efficient alternative to solid polymer or titanium fasteners in mid-corrosion scenarios.
