Marshall 693-5016 - Tube 15 x 6.00-6 W/TR6 Valve

The TR-6 is a threaded metal stem used primarily on ATV tubes. ATV applications use the TR-6 stem due to the low air pressure ATV tires run. The threaded stem is needed to keep the stem from pulling back inside the wheel as the tire flexes. Both nuts and washers go on the outside of the wheel. The first nut is finger tightened only, the second nut is used as a jamb nut to lock the first nut in place.
