A method of making a seal of the type which includes a rigid case, a first seal portion of an elastomeric material and a second seal portion of a low friction material. The method includes placing the rigid case, a wafer of low friction material and two elastomeric blanks into a mold, closing the mold to maintain the aforementioned case, blanks and wafer in position and thereafter further closing the mold to form the seal.

A method for making a seal having a sealing lip portion lined with a low friction material and a body made of an elastomeric material comprising the steps of: placing a rigid annular case in a mold; placing a first ring of uncured elastomeric material in said mold on one side of said case; placing a second ring of uncured elastomeric material in the mold at a location radially spaced from said case, said second ring being disposed adjacent an axially opposite side of said case from said first elastomeric ring; placing an annular wafer of low friction material on one side of said second ring; closing and heating the mold to cause said first ring to bond to said one side of the case and flow both away from the annular wafer across said one side to fill a first portion of the mold and toward the second ring; bonding said wafer to the second ring as said second ring flows along the wafer toward the first ring filling a second portion of the mold; joining the first ring and the second ring at a location between said case and said wafer to form an integral body; and maintaining said mold at a temperature sufficient to substantially cure the first and second rings of uncured elastomeric material.
