- Truck valve, tubeless. 20,5mm rim hole.
Truck Tubeless Valve V3-18-1, Double-Bent (Ø20.5mm)
Screw-in valve, double-bent stem | For tubeless truck, industrial, bus, and trailer wheels | Rubber seal, spring-loaded core, and cap included | Sold per piece
The V3-18-1 is a metal, screw-in valve with a double-bent stem, built for tubeless wheels on trucks, industrial vehicles, buses, and trailers. The mounting hole measures 20.5 mm and the base 31 mm; the valve's overall length is 103 mm at a height of 22 mm.
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 V3-18-1 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 stem is double-bent — it has two bend sections instead of one — which lets the inflation tip route around an obstruction, such as a suspension component or hub housing, giving easier access when inflating than a straight or single-bend valve. 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 does "double-bent" mean for this valve?
The stem has two bend sections instead of one, letting the inflation tip route around an obstruction such as a suspension component or hub housing. It works on wheels where a straight or single-bend valve wouldn't clear the neighbouring part.
What mounting hole sizes fit this valve?
The V3-18-1 has a 20.5 mm mounting diameter and a 31 mm base. 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.
