Product Overview

The TR618A Clamp-In Air/Liquid Valve Stem is a heavy-duty valve designed specifically for agricultural, industrial, and off-road equipment that utilize liquid ballast in tubeless tires. Commonly installed on tractors, graders, loaders, and other heavy equipment, the TR618A features a removable CH-3 core housing, allowing a large opening for quick filling or draining of water, calcium chloride, beet juice, or other liquid ballast. Constructed from solid brass with a durable EPDM rubber grommet, the TR618A provides reliable sealing and corrosion resistance while supporting operating pressures up to 90 PSI.
