Brass Short Shank Type Fitting, 0.50 Inch Hose ID to 3/8-18 NPSM Female NPT Swivel, Straight

It’s a short shank brass hose barb made for 0.50 inch hose ID, and the threaded end is 3/8-18 NPSM female swivel (female NPT swivel style).

Close, but worth clarifying. The swivel end uses 3/8-18 NPSM threading, which is straight mechanical thread rather than tapered NPT. NPSM and NPT share the same thread pitch and diameter, so they will engage, but NPSM relies on a sealing surface or gasket at the face rather than thread taper interference. If your port is a standard 3/8 NPT, make sure there is a proper mating surface for the swivel to seal against.

Primarily designed for low-pressure fluid transfer, suction, and discharge, this brass fitting should suit your needs in those applications.
