Dataseal designs and manufactures PTFE and other high-performance polymer composite spring-energized seals in inch and metric sizes for linear or reciprocating rod and piston sealing applications, for rotating shafts and bores, and for static and axial face sealing applications of low and high viscous liquids and gaseous media under low and high pressure up to 10,000psi (690bar), including vacuum sealing. A highly efficient seal is created as the system pressure increases enough to take over from the spring and engage the shaft or bore. The spring or energized seal assembly provides permanent resilience to the seal jacket and compensates for jacket wear, hardware misalignment and eccentricity. DataSeal offer PTFE-Teflon compounds specific to the application i.e. cryogenic seals, high temperature seals, and PTFE seal alloys with fillers such as PTFE Graphite, PTFE Polymide, PTFE Carbon.
Spring-energized seals made of PTFE are characterized by:
Low and high temperature resistance (-328°F to 500°F, -200°C to 260°C)
FDA compliant compounds and designs available
Exceptional resistance to chemicals and corrosion
Provide the lowest coefficient of friction of all sealing materials
Unlubricated dry-running capabilities
Pressure for standard designs up to 3,000psi (210 bar)
High pressure special seal designs up to 20,000psi (1380bar)*
Applications of Dataseal’s Spring-Energized PTFE Seals are suitable for service in the following industries:
