## Abstract

A conduit coupling assembly facilitates connection of liquid-tight tubing with a conduit section through which associated electrical wiring and/or cables are routed. The assembly includes a transition coupling, which is joined to male and female, liquid-tight connectors. The coupling assembly is joined to the conduit and projects above an associated concrete slab or the like to position the liquid-tight connectors for efficiently joining associated liquid-tight tubing to the conduit. The conduit coupling assembly thus particularly facilitates routing of wiring from a conduit section positioned within a concrete slab or like flooring element, through the transition coupling, and the liquid-tight connectors.

## Claims

### Claim 1

A method of forming a coupling assembly, comprising the steps of:
providing a conduit in an associated building slab so that said conduit projects from the surface of the slab;
cutting a portion of said conduit which projects above the surface of the slab;
cutting said conduit at an inside surface thereof to form a connection region;
providing a transition coupling;
inserting said transition coupling into said connection region of said conduit, and securing said transition coupling to said conduit; and
providing cooperating male and female connectors, and joining one of said connectors to said transition coupling, to thereby facilitate joining the other of said connectors to said conduit in the associated slab.

### Claim 2 (depends on 1)

A method of forming a coupling assembly in accordance with claim 1, including cutting said conduit at the inside surface thereof by reaming said conduit.

### Claim 3 (depends on 1)

A method of forming a coupling assembly in accordance with claim 1, including cutting said conduit at the inside surface thereof at a taper.

### Claim 4 (depends on 1)

A method of forming a coupling assembly in accordance with claim 1, including joining said male connector to said transition coupling.

### Claim 5 (depends on 4)

A method of forming a coupling assembly in accordance with claim 4, including
providing a male thread formation on an exterior surface of said transition coupling, and providing a female thread formation on an interior surface of said male connector, and engaging said male and female thread formations for joining said male connector to said transition coupling.

### Claim 6 (depends on 5)

A method of forming a coupling assembly in accordance with claim 5, including providing an adhesive for adhering said male and female thread formations to each other.

### Claim 7 (depends on 1)

A method of forming a coupling assembly in accordance with claim 1, wherein said transition coupling comprised polyvinyl chloride.
