Mosmatic Fitting 51.354 - M18x1.5M (12-L) to 3/8" NPTF

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.

Applications:

• Hybrid hydraulic and high-pressure cleaning systems
