PTFE FlexiSeal®
The FlexiSeal is a spring-energized U-cup utilizing a variety of jacket profiles, spring types and materials in Rod & Piston, Face and Rotary seal configurations. FlexiSeals are used where elastomeric seals fail to meet the temperature range, chemical resistance or friction requirements. Jacket profiles are made from PTFE and other high performance polymers. Spring types are available in corrosion-resistant metal alloys, including stainless steel, Elgiloy® and Hastelloy®. Standard FlexiSeals are precision machined to fit inch/fractional and MIL-G-5514 glands. Standard and custom sizes in multiple geometries are available from 1/8" to 72" diameters.

FlexiSeal Rotary Seals

The Rotary FlexiSeal should be used when speeds are relatively low (<1000 sfpm) and pressures are high (up to 10,000 psi). FlexiLip™ and FlexiCase™ profiles should be used when pressures are low and speeds high. 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 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.

Applications
Radial applications with extreme conditions that involve lower speeds and higher pressures, for which the Rotary FlexiSeal is best suited, include:

Markets
Since the FlexiSeal solves problems along several parameters, it can be found in virtually every market including:
