Richards Ceramic insulators are
made
from the
highest
quality raw materials and carefully blended for superior
mechanical
strength,
resistance
to thermal
shock
and excellent insulating
properties
at
high
temperatures.
Strict attention
to
hole size,
wall
thick-
ness, and other details result in minimum breakage during
installation.
Our oval type insulators are designed to allow two
thermo-
couple
elements
to be
installed in
a single
protection
tube.
The part numbers below
describe
the physical dimensions of the
insula-
tors.
Example: The
part
number
823-0
signifies a
8
gauge
insulator,
two
holes,
three
inches long,
oval
in shape.
