Overview
The Midland 20028A is a 1/4 in. brass push-in union tee that branches or merges three 1/4 in. tube runs from one compact body. Every port grips and seals its tube by hand, so you can add a branch to an air or fluid line in seconds with no flaring, threading, or sealant. Solid brass construction delivers reliable, corrosion-resistant performance.
