· I-flon(PP) is used
for sliding material.
This packing ha low
frictional resistance,
eliminating stick slip and
assuring high wear
resistance.
Installation space is saved
because of bidirectional sealing ability by single
packing |
· This is a standard
type of combination seal for wide range application. |
