Valve. The valve is a mechanical device which allows
inflation/deflation and retention of the pressurised
air inside an inner tube (or a tyre in the case of
tubeless tyres). It consists of three parts: the valve
cap (a) (to protect the internal mechanism from dust
and ensure an airtight seal), an internal mechanism
(b) and the base (c) (outer coating).
Tubeless Inflator. An inflation system which simpli-
fies the inflation of tubeless tyres.
Bead insertion. Operation which takes place during
inflation and ensures perfect centring between the
bead and the edge of the rim.
Bead pressing gripper. A tool intended for use dur-
ing mounting of the top bead. It is fitted so that it
grips the shoulder of the rim and holds the tyre's
top bead inside the drop centre. It is generally
used for mounting low profile tyres.
Discharge regulator. Union allowing regulation of
the air flow.
Bead breaking. Operation in which the bead of the
tyre is detached from the edge of the rim.
