Greene, Tweed's Enerlip® Seal combines low breakaway friction, reduced leakage and easy installation with a mating PTFE-type heel bearing. The Enerlip HP has an additional anti-extrusion ring. At low pressure, the Enerlip functions as a partially capped, single-acting elastomer lip seal. At high pressure, the Enerlip acts as a pressure-activated PTFE seal, with optimum sealing action at pressures from 0 to 5000 psi (0 to 350 bar).
