This hubcap houses air passage components that distribute regulated air to individual wheel positions while shielding internal routing points from outside exposure. The housing attaches to the hub face and forms a sealed chamber that supports inflation distribution functions through normal road use. Built for trailer wheel-end inflation setups, it supports consistent air routing to the rotating assembly. For wheel-end air routing that needs a protected hub interface, the Hendrickson S-33377 keeps the hubcap pathway aligned with tire inflation system routing requirements.
