A Solution for Virtually Every Market
Since the FlexiSeal solves problems along several parameters, it is used in virtually every market. Examples of extreme condition applications that involve lower speeds and higher pressures for which the rotary FlexiSeal is best suited include:

PTFE FlexiSeals
Different spring designs are available to energize the PTFE jacket: V-shaped cantilever springs (V-Series) and canted coil springs (C-Series). The helical spring (H-Series) should only be used for static or very slow rotary applications.
Rotary FlexiSeals feature either a flanged design or an O-ring on the OD to keep the seal fixed in the bore as the shaft rotates. The O-ring can either be centered along the OD or may be located in the heel of the seal. Virtually any O-ring material can be supplied with a custom rotary FlexiSeal, but a fluorocarbon material is standard.
