A handle assembly includes a handle, a handle seal recess, and a hub engaging portion. A hub has a lock receiving surface and a handle engaging portion. A shaft is receivable within the hub and has first and second ends, the first end engaged with the handle, and the second end rotatable by rotating the grasping portion of the handle. A V-ring is disposed within the handle seal recess and engages the hub to prevent moisture ingress between the handle and the hub. The hub has a seal recess and an X-ring and an O-ring disposed therein to seal against the shaft to prevent moisture ingress between the hub and the shaft. Axial pressure applied to the O-ring by the hub engaging portion of the handle causes the O-ring to press against the X-ring to force at least one lobe of the X-ring against the central portion of the shaft.
