BETA Tyre Valve Lever

BETA offers this valve. The valve is the small tube you inflate the tyre through. Inside it, the core is a screw-in check valve that lets air in and stops it getting out; the cap keeps mud off the core and adds to the seal.

Why replace the valve, core or cap?

The benefits:

• A new core cures the slow leaks that let the tyre down for no obvious reason.
• A new tubeless valve, matching the rim hole diameter, stays airtight despite impacts and vibration.
• Depending on the model, a stronger alloy cap or an indicator cap that shows a drop in pressure at a glance.

Why choose BETA?

BETA (Beta Utensili) is an Italian maker of professional tools founded in 1923, based in Sovico, near Milan, since 1939 and still run by the Ciceri family. The group makes its tools in its own factories in northern and central Italy.

When should you replace this part?

A split, bent or leaking valve, a hissing core, a lost cap: replace them; on a tubeless rim, ideally change the rubber valve at every tyre change.
