ABSTRACT:
A stripper rubber for oil and gas wells, water and geo-thermal wells, having an interior surface design which includes a circular, convex knee portion in the throat area of the stripper rubber to provide additional support to the stripper rubber during insertion of a tubular member through the stripper rubber. The composition for the stripper rubber includes, in one embodiment, enhanced wear characteristics by the addition of milled fibers of Twaron.RTM. mixed homogeneously throughout the stripper rubber.
