ABSTRACT:
A one-piece, self-lubricating, thermoplastic sealing member suitable for a single action piston pump, the sealing member comprising a tubular shaped body, a peripheral portion of which is radially cut into two flanges of preselected length and thickness. One of the flanges has a shorter radial length and a thinner width than the other flange. The flanges are substantially in registry with one another and are bent, preferably in the vicinity of their respective bases, in the same direction to a preselected angle below 20.degree. relative to a transverse axis of the sealing member. When the sealing member is disposed in an annular space between the piston and the cylinder, the double flange portions of the sealing member are in contact with the annular surface of the cylinder or alternately, with a fixed or moveable shaft, providing two sealing engagements therebetween in seriatim, and the oppositely disposed peripheral portion of the sealing member is secured in the piston, or alternately, in the cylinder.
