TR501OV Truck Tire Valve, Brass Clamp-in Tubeless Valve Stem for Wheels with Oval Rim Hole, Fit Heavy Truck & Trailer
TR501OV=TR501 Oval (OV=Oval elliptical base), specially adapted for truck steel rims with elliptical valve mounting holes (mainstream 16 × 6 KS, 16 × 6.5 LS elliptical wheels), different from the standard round hole TR501; The widened elliptical rubber base perfectly fits the irregular wheel rim hole, solving the problem of poor sealing and slow air leakage of ordinary round hole valves.

How to replace the truck tire valve
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.

Frequently Asked Questions
Can TR501OV and regular TR501 be used interchangeably?
I can't. TR501 is compatible with standard circular wheel hub holes; The TR501OV base is elliptical and is only used for KS/LS elliptical shaped hole steel rings. Mixing them will result in sealing failure and continuous air leakage.
Is this engineering heavy-duty vehicle suitable for this?
Fully compatible, with brass valve body and thickened elliptical sealing base, it is not easily damaged during long-term use in mining areas and long-distance freight transportation.
Can we do our own brand packaging?
Support batch printing of logos and brand information on color boxes, and can be shipped in one piece for neutral packaging in stock.
