FlexiSeal® Rotary Seals

FlexiSeal® Rotary Seals

FlexiSeal® Rotary Seals


Description

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.
