A B S T R A C T ROTARY PIPE COUPLING A rotary pipe coupling with replaceable seals is described. The pipe coupling has a first seal element connected to a first body portion and a second seal element connected to a second body portion. The seal elements are defined stepped seal cavities into which are disposed seals. The first and second body portions are removably coupled to respective outer and inner ball races of a ball race to permit relative rotation of the first and second body portions. The effectiveness of the inner seal can be ascertained by detecting the pressure of fluid at port via a stop valve and passage extending to the interface between the seals. The seals can be replaced, if required, by separating first and second body portions by removing one set of fasteners securing one of the body portions to the bearing unit to expose seal cavities.
