INstal³ing a new gasket or packiNg is
S´P. That's why the pubs rarely say
to
use
a
"newµ
gasket
iN
each
maiNteNaNce operatioN.
¶heN you latch onto New gasKets
and 0·riNgs, eyebalL them fOr obvious
cUts, nicks aNd flaws¸ Throw out aNy
=²
If oNe of the new AH¹ºS Models is
faulty oNes.
¶hy do you need new parts each
³
time?
¶eLl,
a
used
gasket

beeN
compressed and woN't give you a good
seal.

are
guaraNteed
with a
reused gasket.
0¹riNgs also take a permaneNt set
that caN½t be duplicated a second time .

a recess to give you a good seal¸
Mounting a gasket rarely preseNts
a

the entire 0¹riNg.

ring goiÃg into a hydraulic system
with hydraulic fluid¸ ¶ork the 0¹riNg
carefUL

sharp
corNers.

or
twisting of the 0¹riNg, either.
Yessir·eÄe¹e,
those
iNexÅeNsive
