Zusammenfassung:	An annular seal for a low friction bonded piston seal is provided. The annular seal having a central axis and including an annular seal body symmetrically positioned about the central axis. The annular seal is integrally molded to the body and provides a lower seal lip body, and a top seal lip. The top seal lip including a first radial lip thickness T1 and a second radial lip thickness T2. A ratio between second radial lip thickness T2 to first radial lip thickness T1 is less than 1.00. The annular seal includes a radial lip height H, and a radial lip overall pressure received thickness T3. A ratio of radial lip height H to second radial lip thickness T2 is greater than or equal to 0.65. The radial lip overall pressure received thickness T3 is less than or equal to 0.8 mm. The first radial lip thickness T1 is less than or equal to 0.7 mm.
