Ham-Let 766L Straight Fitting — Female NPT

Instrumentation fitting (Series 766L) designed to join tubing with a tight seal using the Let-Lok double-ferrule compression system, delivering high-performance, leak-proof sealing in high-pressure fluid systems. The tube end uses the Let-Lok double-ferrule compression system—no welding or flaring required—for a leak-proof seal, while the Female NPT threaded end connects to the line.

Thanks to its rugged 316 stainless steel construction, it is the ideal choice for withstanding corrosive environments, vibration, high temperatures and critical pressures. It is used especially in control panels, sampling lines, refineries and industrial automation systems. Also available in brass for less demanding applications.
