Designed for robust farm tractor and road grader tires, these TR618A tubeless tire air liquid valves feature a metal clamp-in type for easy liquid ballast filling. Installation is straightforward, enhancing user convenience and efficiency in agricultural settings. Constructed from solid brass and fortified with EPDM rubber, these valve stems resist rust and corrosion effectively. They are durable, not prone to breakage or deformation, and fit all standard 5/8inch valve stem holes. Complete with core housing (CH-3), high-temp valve core, hex nut, washer, rubber grommet, and cap, these TR618a Valve Stems support a maximum pressure of 90 PSI. The CH3 core housing can be removed for a larger opening, facilitating easier air or liquid filling. Chrome caps feature rubber O-rings compatible with Schrader valve cores. The metal clamp-in type valves simplify the process of filling with liquid ballast, allowing for both liquid ballast and air to enter the tire efficiently.
