Foreign Substances in Tires
Tires which have been in service may contain foreign substances such as leak
sealers. It is important that these substances are not pulled into the NitroPro unit
during the vacuum procedure, resulting in possible performance issues and costly
repairs not covered by RTI’s warranty.
When servicing a vehicle, first check the valve stems and valve stem caps for any
type of fluid or foreign substance. Install deflators and allow all four tires to deflate
to zero pressure. Then check the deflators for any indication of fluids or foreign
substances.
Do not use the NitroPro vacuum procedure on any tire where evidence of fluids or
foreign substances are detected on the valve stems, valve stem caps or deflators.
Instead, follow a four step “deflate-inflate-deflate-inflate” process to achieve
desired nitrogen purity.
