ETUDouble-acting Piston Seals

Double-acting O-Ring energized piston seals for critical applications, fluid/gas separation or low density fluids. Those seals consists of a PTFE compound sliding surface with an incorporated Q-Ring, both energized by an O-Ring. It minimizes the stick-slip phenomena, guarantees a low friction and a very high wear resistance together with a good sealing action. Standard materials: filled PTFE + Nitrile
