Spring energized seals excel in applications with high-speeds, wide temperature ranges and those with corrosive media.
Our Spring energized PTFE Seals are classified as follows:
Springs have three types: Cantilevered spring, Helical spring, Canted coil spring.
Trisun 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.
