Each IVS service kit comes with two (2) rubber grommet sizes: one (1) fits 0.453” diameter wheel valve
holes and one (1) fits 0.625” diameter wheel valve holes. The IVS should be installed using a single
grommet only. WARNING! – Do NOT use both sizes of the included rubber grommets to install a single
valve stem. Please check and make sure that the correct grommet size is used for the valve stem and fits
the wheel’s valve hole diameter prior to TPMS sensor installation.
The IVS service kit comes
pre-assembled with the
0.625” diameter rubber
grommet; metal washer;
0.625” diameter nut and valve
cap on the valve stem and
includes a separate 0.453”
diameter grommet and nut in
the polybag.
Please use the pre-
assembled 0.625” diameter
grommet on the valve stem if
the wheel valve hole is 0.625”
diameter.
When the valve hole of the wheel is
0.453” diameter, disassemble the
pre-assembled IVS valve stem.
Remove the 0.625” diameter rubber
grommet, metal washer, nut from
the valve stem. Assemble the
0.453” diameter grommet, nut and
cap in order.
