Product description

Piston seals are used in hydraulic cylinders for fluid sealing. Piston seals are installed in the cylinder head and seal against the cylinder bore to ensure that pressurized fluid does not leak across the cylinder head. This allows pressure build up on one side of the piston, making the cylinder extend or retract.
Piston seals are available as double-acting or single-acting components. For double-acting cylinders, with pressure on both sides, double-acting seal systems are required. These types of seals typically have a symmetrical shape and have the ability to provide sealing capabilities in both directions.
Single-acting piston seals are designed for and used in those cylinders where pressure is applied from one side only.
Seals-Shop.com offers piston seals that are available as O-Ring energized Polytetrafluoroethylene (PTFE) products where the focus in the design is on low friction, compact form and simple installation.
