PSI HUB CAP

This is a heavy-duty wheel-end hub cap designed for oil-lubricated axle systems. It features a side fill plug for convenient oil checks and refills, along with a clear, cloud-free sight window that lets you easily monitor oil level and condition at a glance. You would replace your hub cap if the window is cracked or clouded, the gasket is leaking, or the cap is damaged, to prevent oil loss and bearing failure. The part includes coated mounting bolts and a new gasket for a leak-free installation.
