ABSTRACT:
A corrugated pipe saddle gasket is provided having a leading member, a primary sealing member, and an arm member, with the gasket having a contoured surface extending along at least a portion of the bottom of the primary sealing member and the arm member corresponding to the shape of a corrugated pipe. The primary sealing member of a second length is intermediate the leading member of a first length and the arm member of a third length, with the third length being greater than the sum of the first and second lengths. The gasket has at least a portion of its arm member having a durometer different from the durometer of the primary sealing member. In the preferred embodiment, the arm member has an axis that is substantially horizontal, and the leading member has an axis that is substantially vertical, such that the two axes are substantially perpendicular. The primary sealing member has a beveled portion, a sloping portion, and an end wall, with the sloping portion being between the beveled portion and the end wall. The leading member has a bottom surface, a channel, and a leading face having top and bottom edges.
