Advantages of a One-Piece Seal
Parker’s LC Profile Seal offers several advantages over
more traditional two-piece seal geometry. The problem
with traditional two-piece seals occurs at installation and
in service, during rapid fluctuations in pressure where
expander rings can become partially dislodged -
resulting in leakage. The LC Seal’s unique one-piece
construction eliminates problems associated with seals
containing rubber expander rings used to load the seal
lips to maintain leak-free operation.
