A measuring device includes a generally tubular, flexible body with opposite ends and a longitudinally-extending bore. The body includes a plurality of measuring indicia at regularly-spaced intervals therealong. It can be selectively mounted on the body ends and have a predetermined length which corresponds to the measuring indicia spacing. An extension connector is also provided for connecting two measuring device bodies together. A centering assembly has a sleeve which receives the body and wings projecting radially outwardly therefrom for generally centering the measuring device within a pipe bore.
