Brass Short Shank Type Fitting, 0.38 Inch Hose ID to 1/8-27 Male NPT, Straight

It matches a 0.375 inch (3/8 inch) hose ID on the barb side and a 1/8-27 male NPT thread on the other end, in a straight configuration.

This fitting is designed for low-pressure fluid transfer, suction, and discharge applications, making it suitable for general shop use.

The hose end is sized for 3/8 inch ID hose, and the male thread is 1/8-27 NPT, which is a common standard size you'll find on a lot of ports and fittings in light-duty fluid systems. As long as your hose ID is 3/8 inch and your port accepts 1/8 male NPT, the two ends should line up without any adapter needed. Just make sure you're using the right clamp and seating it properly, since working pressure on shank fittings like this one depends heavily on how well the clamp is installed, not just the fitting itself.
