Pipe passage switch, characterized essentially by the fact that its body, generally tubular, has one of its ends provided with internal and external thread, forming internally a partition with a passage coinciding with that of the ball valve that dock at this point with interposition of a joint; seal that is repeated on the other side of the valve, this joint being retained by a threaded sleeve to the body with sufficient pressure with respect to the valve; with the particularity that said sleeve receives an extension, threaded, that pushes on a flat gasket and this on an O-ring that upon closing closes on a pipe introduced in the sleeve.
