1/2 in. x 1/4 in. Barstock Compression x Male Elbow
Overview
The Midland 18236B is a barstock 90-degree elbow connecting 1/2 in. OD tubing on the compression end to a 1/4 in. male NPTF port. It reduces a larger 1/2 in. tube run down to a small 1/4 in. threaded outlet, with a 11/16-20 x 1/4-18 thread combination and a 200 psi rating. The solid-brass barstock body suits copper, aluminum, and thermoplastic tubing.
