Hydraulic Piston Seals
The hydraulic piston seal's job is to prevent pressurized fluid or other media from bypassing the piston when system pressure drives the piston down the cylinder during a pressure cycle.
We offer a wide range of hydraulic piston seal designs, such as hydraulic lip seals, hydraulic PTFE cap seals, compact-squeeze type hydraulic seals, and application-specific designed hydraulic seals made from high-performance elastomers and engineered plastic materials to provide maximum durability and sealing performance.
Our Hydraulic Piston Seals are classified as follows:
According to the pressure:
 High-Pressure Piston Seals – up to 5,000psi (350bar)* |
Ultra-High Pressure Piston Seals – up to 10,000psi (700bar) |
| Long-Life Piston Seals – up to 5,000psi (350bar)* |
Low-Friction Piston Seals – up to 5,000psi (350bar)* |
According to the direction of acting:
Single-acting – or Uni-directional – Hydraulic Piston Seals capable of sealing dynamic pressure from one side.
Double-acting – or Bi-directional – Hydraulic Piston Seals capable of sealing dynamic pressure from both sides.
Double Acting Hydraulic Piston Seal - PS10
Double Acting Hydraulic Piston Seal - PS10 DESCRIPTION Piston Seals or Piston Rings are used to seal fluids in hydraulic cylinders. They are located within the cylinder head and seal against the cylinder bore, preventing fluid from passing through. This permits pressure to build up on one side of the piston, causing it to expand or retract. A double-acting hydraulic piston seal provides the best sealing capacity of a double-acting cylinder, capable of sealing dynamic..
Single Acting Hydraulic Piston Seal - PS11
Single Acting Hydraulic Piston Seal - PS11 DESCRIPTION Piston Seals or Piston Rings are used to seal fluids in hydraulic cylinders. They are located within the cylinder head and seal against the cylinder bore, preventing fluid from passing through. This permits pressure to build up on one side of the piston, causing it to expand or retract. It is usually advisable to use the type of seal intended to give optimum sealing characteristics for single-acting functions for..
Double Acting Hydraulic Piston Seal - PS12
Double Acting Hydraulic Piston Seal - PS12 DESCRIPTION A double-acting hydraulic piston seal provides the best sealing capacity of a double-acting cylinder, capable of sealing dynamic pressure from both sides (bidirectional). A hydraulic piston design with two single-acting seals on the piston for a double-acting cylinder is prone to failure. The reason for this is because extremely high pressures can become trapped between the seals. Piston Seals or Piston Rings are..
Double Acting Hydraulic Piston Seal - PS13
Double Acting Hydraulic Piston Seal - PS13 DESCRIPTION Piston seals, also known as piston rings, are used in hydraulic cylinders to guarantee that pressurized fluid does not leak over the cylinder head when the system pressure pulls the piston down the cylinder bore. Double-acting piston seals are suitable for a variety of cylinder applications and operating circumstances. They can be pressured from both sides, either solely from one side or, in the case of different..
