One illustrative method disclosed herein includes positioning a first tubular adjacent a second tubular, wherein one of the first and second tubulars includes a plurality of radially deflectable fingers formed in an end thereof, mating the first and second tubulars into mated engagement with one another, wherein, during the mating of the first and second tubulars, the radially deflectable fingers deflect in a radial direction, and expanding the first and second tubulars by forcing an expansion mandrel through the mated first and second tubulars such that the expanded first and second tubulars have an expanded inside diameter that is greater than an initial inside diameter of the first and second tubulars.

The embodiments shown provide a coupling apparatus and method of use to enable fluid communication between a multi-port mechanical switch and a primary dive regulator. The apparatus includes a grooved portion configured to be releasably attached to a multi-port mechanical switch and a leading edge dimensioned to be releasably secured onto a primary dive regulator. The method includes providing the apparatus with the multi-port mechanical switch and primary dive regulator and compressing or extending onto the first end into the multi-port mechanical switch, and extending a second end onto a primary dive regulator to create a hermetically sealed channel for fluid communication through the apparatus.

A length of pipe and methods of connection that provide a flush, continuous external wall on adjacent lengths of pipe. Each individual length of pipe includes opposed male and female ends. Generally, the female end is dimensioned such that the male end of an adjacent length of pipe is slidably insertable into the female end. When the male end has been fully inserted into the female end, an exterior surface on each of the adjacent lengths of pipe is arranged to define a flush engagement such that an assembled exterior surface defines a continuous, planar surface absent any projections or enlargements. By avoiding any diameter increase at a connection point, the resulting pipe can be more easily installed and/or positioned via sliding or lifting there are no enlarged or projecting portions that can hinder movement of the assembled pipe.
