ABSTRACT:
An integral conduit section of a multiple conduit system includes an outer housing having a straight coupling portion at one end and a belled coupling portion at the other end, a plurality of innerducts disposed in a parallel manner within the outer housing, one or more spacers for parallely positioning said innerducts in the outer housing, and a three-piece innerduct coupler disposed within the belled portion of the outer housing and engaged with the trailing ends of a plurality of innerducts, being linearly interconnectable with like conduit sections. The innerduct coupler includes a guide for facilitating entry of the plurality of innerducts of an adjacent conduit section into a like section; a seal that creates an air and water tight seal between the adjacent innerducts when like sections are interconnected, without the need for cement or sealing lubricants; and a seating component that terminally positions the innerducts in the innerduct coupler upon the interconnection of like integral conduit sections.
