Truck Tubeless Valve V3-12-01 40MSF (Ø15.7mm)
Bent, screw-in metal valve | Rubber seal and spring-loaded core included | Metal cap with seal | Sold per piece
The V3-12-01 40MSF is a metal, screw-in valve built for tubeless wheels on trucks, industrial vehicles, buses, and trailers. It has a clearly bent profile and a wider base (Ø 26 mm) that seats against the rim, while keeping the same 15.7 mm mounting hole as the rest of this valve group — a combination that makes inflating and checking pressure easier even where access is limited.
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 V3-12-01 screws in from outside the rim, and the rubber seal, compressed by the mounting nut, conforms to the mounting hole and blocks air from escaping along the stem. The wider base spreads the load more evenly against the rim, which matters under the heavier loads typical of trucking use. 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 straight into the rim hole, no connector needed.
Easier to reach for inflation on tight wheel setups.
Stable seating against the rim surface.
Comes with a protective cap with seal.

Frequently asked questions
How does this valve differ from the TR-570C?
Both are bent and share the same 15.7 mm mounting hole, but they differ in overall dimensions and base width. The V3-12-01 40MSF has a larger, clearly specified base (Ø 26 mm) along with separate overall height (22 mm) and length (55 mm) figures, while the TR-570C's listing gives only a single overall length of 51 mm with no separate base measurement.
What's the point of the wider base?
A wider base rests on more of the rim surface, which helps spread the load evenly both when tightening it down and during use — useful under the heavier loads typical of truck wheels.
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 both the hole itself and the clearance around it is worth doing before ordering, so the base seats properly against the rim.
Are any extra parts needed for installation?
No. The V3-12-01 40MSF 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.
