Abstract
A swivel joint includes a tail section and a body portion that define a passageway therethrough and which can rotate relative to one another. One or more seals and bearings can be disposed between the tail section and the body portion. An electrical conductivity grease fitting can be mounted within a bore hole in the body portion. The electrical conductivity grease fitting can have a lubricant passed therethrough to lubricate the bearings. The electrical conductivity grease fitting has a first portion in electrical communication with the body portion and a second portion that is biased into electrical communication with the tail section to maintain electrical conductivity between the tail section and the body portion.
