RED Flat Base Valves 40mm TY BIKE

The “Flat Base” means a firm airtight fit is easily achieved without cranking on the locking nut with a pair of pliers.

The internal seal is made of soft malleable rubber & is multi-shaped to fit most MTB rims. 

The seal is not fixed to the valve, making valve removal a doddle if you need to fit an emergency tube.  

Large locking nut with oversized rubber O-ring secures the valve without damaging the rim.

Aluminium valve cap, valve core tool included.  ​​​

For best results use Flat Base valves with Tyre Yogurt sealant !
