FlexiSeal (FCC FCS FHC FHS FFC FFS FFN), Spring Energized PTFE Lip Rotary Shaft Seals

FlexiSeal (FCC FCS FHC FHS FFC FFS FFN), Spring Energized PTFE Lip Rotary Shaft Seals

Brand: Parker Hannifin

Parker’s rotary shaft FlexiSeal™ designs feature either a flanged design (FFC FFS FFN) 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 (FCC FCS) or located in the heel of the seal (FHC FHS). 

Virtually any O-ring material can be supplied with a custom rotary FlexiSeal, but a fluorocarbon material is standard.
