I will need to call the factory for their official number, but it is higher than 120 psi. These extenders are used on 22.5 truck tires that run 120 psi at normal temps and much higher as the heat rises.
UPDATE: Spoke to the factory and they do not have a maximum PSI rating for their extensions. They did say that these products are used on 22.5 tires with max fill pressure of 140 psi and have not had any issues.
