Perfect Engineers, through its premium brand PE-LOCK, is a leading manufacturer and global exporter of Hastelloy Ferrule Fittings—engineered for the most aggressive chemical environments, high-purity applications, and high-pressure process systems. These fittings are designed to provide unmatched resistance to acids, oxidizing agents, and chloride-induced corrosion, where standard stainless steels, Monel, or Inconel may fail.
Built to withstand temperatures up to 600°C and pressures up to 10,000 PSI, PE-LOCK Hastelloy fittings are trusted by the chemical processing, pharmaceutical, pulp & paper, nuclear, and marine industries worldwide.
Hastelloy Ferrule Fittings are advanced compression-type connectors made from nickel-molybdenum-chromium alloy grades like:
These fittings use a double ferrule sealing system that creates a gas-tight, leak-free, and vibration-resistant connection. They are specifically designed for highly acidic, oxidizing, and chloride-rich media, especially in applications involving hydrochloric acid, sulfuric acid, ferric chloride, and hypochlorites.
