Mosmatic 51.354 High-Pressure Fitting – M18×1.5 Male (12-L) to 3/8″ NPTF Female

Description

• The Mosmatic 51.354 VER Fitting is a high-pressure stainless steel adapter designed for hybrid systems that combine metric profile ring connections with NPTF threads. With a M18x1.5 male thread and 12-L profile ring sealing surface on one end and a 3/8″ NPTF female thread on the other, this fitting ensures safe, leak-proof performance up to 7300 PSI.

  The profile ring face (12-L) allows for precise O-ring sealing against flat-face mating surfaces in metric hydraulic setups, while the NPTF (National Pipe Taper Fuel) thread provides a secure dry-seal connection to standard U.S. components.
