Abstract
A seal for connecting between oval cross-section pipe sections includes an oval shaped tubular insert having two flat wall sections connected to one another by two end curved sections. The oval-shaped tubular insert has a pair of ends with a passage extending through the pair of ends. An elastomeric over-mold is provided on an exterior of the oval-shaped tubular insert. The elastomeric over-mold includes a pair of raised seal beads each surrounding a respective one of the pair of ends. The pair of raised beads have a first bead thickness in a radial direction along the two flat wall sections and a gradually increasing bead thickness from the ends of the flat wall sections to a center of the two end curved sections.

A plug & seal for connecting between oval cross-section pipe sections, comprising:
- an oval-shaped tubular insert having two flat wall sections connected to one another by two end curved sections, the oval-shaped tubular insert having a pair of ends with a passage extending through the pair of ends;
- and
- an elastomeric over-mold on an exterior of the oval-shaped tubular insert, the elastomeric over-mold having a pair of raised seal beads each surrounding a respective one of the pair of ends, wherein the pair of raised beads have a first bead thickness in a radial direction along the two flat wall sections and a gradually increasing second bead thickness from the ends of the flat wall sections to a center of the two end curved sections.
A pipe system, comprising:
- a pair of oval pipes each having an oval cross-section and an open end;
- and
- a plug & seal for connecting between the open ends of the pair of oval pipes, the seal including an oval-shaped tubular insert having two flat wall sections connected to one another by two end curved sections, the oval-shaped tubular insert having a pair of ends with a passage extending through the pair of ends, and an elastomeric over-mold on an exterior of the oval-shaped tubular insert, the elastomeric over-mold having a pair of raised seal beads each surrounding a respective one of the pair of ends, wherein the pair of raised beads have a first bead thickness in a radial direction along the two flat wall sections and a gradually increasing second bead thickness from the ends of the flat wall sections to a center of the two end curved sections.
