R&P Knowledge Hub
Oil bath hubs rely on a sealed oil cap to retain lubricant inside the hub cavity. The O-ringprovides the sealing surface between the aluminum oil cap and hub body. Over time these sealscan flatten, crack, or become brittle due to heat and oil exposure.
Replacing worn O-rings during routine hub inspection helps prevent oil leakage and contaminationof the hub bearings. Always verify oil cap model numbers and seal diameter before ordering.
