It seals the wheel hub, keeping grease in and road contaminants out while the vent relieves pressure to prevent seal damage. Typically used on heavy-duty truck and trailer axles with a 6-bolt hub pattern, this cap is replaced when the existing cap is cracked, leaking, or missing its vent, to protect wheel bearings from failure.
