This brass plug serves many purposes on various Land Rover models. It's most commonly seen in North America as the radiator fill plug on NAS V8 Land Rovers. However, this plug also serves as the thermostat plug on the 300 Tdi engines, and the fill plug on the Disco2's front and rear differentials. Lots of different Land Rovers from the Series III 109 to the Disco2 used this plug or the plastic form of this plug. Common cross-reference part numbers include ERR4686, FTC5403, and KTP9401. Unlike the cheesy plastic plug that came with your Land Rover, this brass model will not deteriorate and fail at the worst possible time. The hex head is the common 13/16" size (the same size as spark plug sockets). ERR4685 O-ring is included.
