ABSTRACT:
A one-piece, self-lubricating, thermoplastic sealing member suitable for a double action piston pump, the sealing member comprising a tubular shaped body, a peripheral portion of which is radially cut into two flanges of substantially equal length and thickness. The flanges are substantially in registry with one another and are bent, preferably in the vicinity of their respective bases, in opposite directions to a preselected angle below about 20.degree. relative to a transverse axis of the sealing member and are symmetrically disposed about such axis back to back in a double cup-like shape. When the sealing member is disposed in an annular space between the piston and the cylinder, the double cup 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 sealing engagements therebetween, and the oppositely disposed peripheral portion of the sealing member is secured in the piston, or alternately, in the cylinder.
