Truck Tubeless Valve V3-21-12 (TR-573C, Ø15.7mm)
Bent, screw-in metal valve | Rubber seal and spring-loaded core included | Metal cap with seal | Sold per piece
The V3-21-12 TR-573C is a metal, screw-in valve built for tubeless wheels on trucks, industrial vehicles, buses, and trailers. It shares its mounting hole with the rest of the Ø15.7 mm valve group in Our range, and at 83 mm overall length it's the longest bent model in that group — a solid choice where the valve needs to reach further beyond the rim.
What this valve is for
On a tubeless wheel, the valve itself — not a separate inner tube — is what keeps the air in, so its condition has a direct bearing on how airtight the whole wheel stays. The V3-21-12 TR-573C screws in from outside the rim, and the rubber seal at the point where the valve meets the wheel is compressed by the mounting nut, conforming to the mounting hole and blocking air from escaping along the stem — the stability and airtightness of the whole valve depend on this connection. The bent shape also makes the inflation tip easier to reach, and its greater overall length compared to shorter models suits wheel setups where the valve needs to sit further out from the rim. A spring-loaded core holds the pressure, and the metal cap with its own seal keeps moisture and grit off it between inflations.
Design and construction
Mounts directly into the rim hole, no connector needed.

Frequently asked questions
How does this valve differ from the TR-570C and TR-571C?
All three are bent and share the same mounting hole (Ø 15.7 mm), but differ in overall length — the TR-570C measures 51 mm, the TR-571C measures 58 mm, and the TR-573C, the longest of the three, measures 83 mm. A longer valve suits situations that call for more reach beyond the rim.
When is a longer valve like the TR-573C the right choice?
A longer valve makes it easier to reach the inflation tip on wheel setups where a shorter model would sit too deep relative to housing components or a drum — comparing the available space against a valve's overall length before choosing a specific model is worth doing.
What rims does this valve fit?
It's built for rims with a 15.7 mm mounting hole, the size typically found on tubeless truck, industrial vehicle, bus, and trailer wheels. Measuring the rim hole before ordering is worth doing to rule out a mismatch.
Are any extra parts needed for installation?
No. The V3-21-12 TR-573C doesn't need a connector or a separate sealing washer — the rubber seal, spring-loaded core, and cap with seal are already included and are all it takes for an airtight fit.
