- Truck valve, tubeless. 20,5mm rim hole.
Truck Tubeless Valve V3-15-1, Bent (Ø20.5mm)
Screw-in valve, bent stem | For tubeless truck, industrial, bus, and trailer wheels | Rubber seal, spring-loaded core, and cap included | Sold per piece
The V3-15-1 is a metal, screw-in valve with a bent stem, built for tubeless wheels on trucks, industrial vehicles, buses, and trailers. The mounting hole measures 20.5 mm. The bent stem keeps the wheel easy to inflate even where access to the valve is restricted.
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 V3-15-1 screws in from outside the rim, and the point where the stem meets the wheel is additionally protected by a rubber seal compressed by the mounting nut — this lets the seal conform to the mounting hole and block air from escaping, forming a stable, airtight connection. The bent stem sets the inflation tip at a more accessible angle than a straight valve, which helps on wheel setups where a straight stem would sit awkwardly or clash with neighbouring components. A spring-loaded core holds the pressure and can be replaced on its own without removing the whole valve from the wheel, while the metal cap with its own seal keeps moisture and grit off it between inflations.

Frequently asked questions
What mounting hole sizes fit this valve?
The V3-15-1 has a 20.5 mm mounting diameter. It's worth measuring the rim hole before ordering, since valves of this type come in several diameters matched to different rims.
Are any extra parts needed for installation?
No. The rubber seal, spring-loaded core, and cap with seal are already included and are all it takes for an airtight fit, without extra washers or connectors.
How do I check the valve is airtight after installation?
The simplest method is applying a leak detection fluid to the inflated tyre — bubbles forming where the valve meets the wheel signal a leak that's worth fixing before the vehicle goes back into service.
