Abstract:
A pipe boot includes a plurality of co-axial hollow cylindrical sections joined by an annular shoulder between successive sections. A first annular bead and a second annular bead surround each tubular section with the first annular bead positioned radially outward of each annular shoulder. The second annular bead is spaced a short distance from the second annular bead leaving an annular trough between them.
