Piston Seals
Piston Seals
For linear and reciprocating dynamic sealing applications
The function of the piston seal is to ensure that pressurized fluid or other media does not by-pass the piston as the system pressure pushes the piston down the cylinder during a pressure cycle.
American High Performance Seals manufactures a comprehensive range of piston seal designs, including lip seals, PTFE cap seals, compact-squeeze type seals and application–specific designed seals made from high-performance elastomers and engineered plastic materials to offer maximum durability and sealing performance.
Piston Seal Design Considerations:
• Pressure Rating…
• Single- or Double-Acting Piston Seals…
• Lip vs. Squeeze Seals…
• Seal Lip Geometry…
• Non-symmetrical Piston Seal Design…
Our Piston Seals are classified as follows:
– 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)*
High-Pressure Piston Seals – up to 5,000psi (350bar)
Typical Applications
Medium duty, linear, reciprocating dynamic sealing applications
Operating Range
Pressure: up to 5,000psi (350bar)*. For pressure above 3,800psi (260bar), please contact engineering for clearances. Pressure ratings can be increased by reducing clearances.
Surface Speed: up to 13ft/s (4m/s)* depending on seal type and material
Temperature: -40°F to 400°F (-40°C to 200°C)* depending on seal material
Materials: high-performance polyurethanes, PTFE, PTFE, engineered thermoplastics, NBR, Nitrile, FKM, Viton®, H-NBR, EPDM, FDA-compliant food grades, low- and high-temperature grades, including proprietary Duralast™, Duraloy™, and Permachem™ compounds.
