GOOD AGING RESISTANCE FLAP FOR PROTECTING INNER TUBE

Item specifics

FLAP

Flap is aslo know as lining belt or mound layer , which is a ring tape used to protect the contact face of inner tube from rim wear .

It is mounted betwee the inner tube and the rim with a thick middle and thinning from inside to outside on both sides.

There is a center line on the outer surface of the flap, which is used for alignment during installation .

There is also a hole in the center line and the inner tube valve nozzle goes through from this hole .

The flap does not require high physical and mechanical properties of the rubber, but it should have good aging resistance .

Tubeless tyres fixed to deep rims and ultra-low pressure tyres fixed to special structural rims are compact and do not require flap .

We can install metal plates in the valve mouth area according to customers requirements.
