Description
Flanged spring energized seal contains a U-shaped sealing element energized with a spring to ensure proper sealing at start up and low pressures. A flange is designed into the seal that mates with the seal housing to mechanically hold the seal in place. Unlike other rotary seals that rely on a press fit, or an o-ring on the OD, this design ensures no seal rotation. This is especially important in applications that see high levels of thermal cycling. This seal can tolerate some of the highest pressure of any rotary seal.
It designed 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.
