Brass 5/16 in. Insert, Lead Free, .1875 OD

Overview

The Midland P-60-INS-5-S is a lead-free brass tube insert (stiffener) sized for 5/16 in. compression fittings with a .1875 in. (3/16 in.) tube OD. It slips inside soft polyethylene or nylon tubing to keep the wall round under the ferrule, so the compression nut makes a reliable, leak-tight seal that will not collapse the plastic tube.
