The invention relates to a gas spring with end position damping having a piston-cylinder unit which is provided with two identically configured pistons arranged in a mirror-like image. Each piston has two axially extending parts defining an annular groove therebetween. The groove is configured to receive an annular sealing ring operative to axially move within the groove. The groove, the pistons and cylinder are configured with an arrangement of flow passages providing damping at the end of the push-in and push-out strokes of the piston.
