Description
The 372-7099 Trailer Oil Seal Kit 4-5/16″ ID is a complete seal kit designed for larger trailer axles that use oil bath lubrication systems. With a 4-5/16″ inner diameter, this kit provides everything needed to properly seal the hub and prevent oil leaks while keeping contaminants out of the bearing area.
