Overview
BUC 5/8" 316 Stainless Steel Bulkhead Union Compression Fitting delivers robust performance in high-pressure environments, combining precision engineering with a double-ferrule design for secure tube retention and leak-tight sealing.
Optimized for compatibility with steam, air, water, oil, gasoline, natural gas, and solvents or acidic media suited to 316 stainless steel.
Key enhancements include a silver-plated nut (NTC) to reduce friction during installation and a surface-hardened back ferrule (BFC) for consistent sealing integrity under dynamic pressures.
Note: Performance characteristics may vary depending on system-specific conditions and temperature fluctuations.
