Heavy Duty Tubeless Air Liquid Valve Stem for Tractor and Agricultural Tires
The TR618A Tire Valve Stem is a heavy-duty air liquid tubeless tire valve designed for agricultural machinery, tractors, graders, loaders, and industrial vehicles. With a durable clamp-in metal structure, TR618A allows both compressed air inflation and liquid ballast filling, providing a reliable solution for large tires operating under heavy loads and demanding working conditions.
Unlike standard rubber snap-in tire valves, the TR618A valve stem features a solid metal body with sealing components, offering excellent strength, corrosion resistance, and long-term durability for off-road and agricultural applications.

Standard Box Packing with Custom Branding Support
LogoCustomized LOGO Carving
Laser engraving of customer trademarks and corporate logos on brass rods and dust caps.
Print customer logos and brand names. Printing brand labels, place of origin, specifications, and moisture-proof labels on cardboard boxes.
Clean, Press and Wait for Strong Adhesion
01Release the air and remove the old valve
Lift up the vehicle, release the tire pressure, remove the tire, and remove the old valve; Clean the rust and residue of the wheel rim installation holes and old sealing rings, and check for any deformation or burrs in the hole positions.
02Assemble a brand new tire valve and seal it
Lock evenly with standard torque to prevent deviation and slow air leakage; Adjust the valve angle to avoid friction with the tire wall, and install a brand new high-temperature resistant valve core.
03Testing+Dynamic Balance Loading
Inflate to the standard tire pressure of the vehicle and check for any air leaks; Perform tire dynamic balancing; Recheck the tire pressure during the loading road test to confirm that there is no leakage or shaking, and then complete the replacement.
Tip: Control the torque and avoid violent twisting. Excessive torque can cause fracturing of the rubber ring and deformation of the wheel rim hole; Insufficient torque leads to turbulence, looseness, and air leakage in the later stage.
Controlled Details from Weight Accuracy to Finished Packing
01Incoming Material Inspection
100% sampling inspection of all raw materials; The spectrometer detects the composition of brass material to eliminate the problems of cracking and corrosion caused by impurities in copper.
02Process Inspection
Micrometer measuring rod length, base diameter, thread; Full inspection of thread gauge to ensure smooth assembly without slipping threads.. Remove semi-finished products that are prone to rust.
03Airtightness Test
High pressure airtight water immersion test: Simulate the working pressure of a heavy truck at 14Bar to maintain pressure, and observe the entire process without any bubbles or leaks; Torque and voltage withstand test.
04Final Inspection
Full inspection of appearance scratches, coating peeling, and laser logo clarity; Control the weight tolerance of the entire machine to ensure stable dynamic balance.
