1.
The
O-ring
is
an
annular
seal
having
an
O-shaped
cross
section,
the
size
of
which
is
determined
by
the
inner
diameter
ID
and
the
wire
diameter
CS.
2.
O-ring
size
calculation:
outer
diameter
=
inner
diameter
+
2
x
wire
diameter
(OD
=
ID
+
2x
CS).
3.
The
purpose
of
using
O-ring
seals
is
to
prevent
leakage
and
loss
of
liquids
or
gases.
4.
O-rings
are
the
most
commonly
used
type
of
seal
because
of
their
simplicity,
convenience,
and
small
installation
space.
As
long
as
the
groove
design
and
material
selection
are
correct,
and
the
operating
conditions
are
within
the
temperature
range
of
the
rubber
material,
the
seal
can
have
a
long-term
sealing
effect
in
the
static
or
dynamic
seal.
