Description
The Midland Industries 620606C is a composite-body DOT push-to-connect male branch Y for air brake systems. The two Y legs accept 3/8″ SAE J844/J1131 nylon air-brake tubing with tool-free push-in connections, while the 3/8-18 male NPT branch threads directly into a valve, manifold, or tank port. The glass-reinforced PBT composite body is UV and vibration resistant and shrugs off road salt that corrodes brass.
