Product Overview
The TR545D Clamp-In Metal Valve Stem is a heavy-duty valve stem designed specifically for 22.5-inch and 24.5-inch Alcoa® aluminum truck wheels and other commercial aluminum wheels utilizing a 0.382–0.390 in. (9.7–10 mm) valve hole. Featuring a 60-degree bend, the TR545D provides excellent accessibility for tire inflation and pressure checks while maintaining a secure mechanical seal through its clamp-in O-ring design.
