Brass Short Shank Type Fitting, 0.31 Inch Hose ID to 1/2-20 SAE 45 deg Flare, Straight

This fitting is designed to connect a 0.31 inch (5/16") ID hose to a 1/2-20 SAE 45-degree flare connection.

Low pressure fluid transfer covers both suction and discharge, so it handles either side of that equation. Just keep in mind the working pressure you actually get out of it depends on the hose itself, how many clamps you're running, where they're placed, and what you're moving through the line. The fitting is machined from free cutting brass CDA 360 alloy, so the metal side of things is solid. The hose and clamp setup is really where your pressure ceiling gets set.
