UNAFFECTED by smoke,
salt fogs and fumes, constant in their electrical
and physical characteristics, *PYREX Radio
Insulators give permanent insulation
for all radio work. They represent the true fusion
of materials resulting in a homogeneous, non-porous
insulator, uniform throughout its structure -- high
in dielectric strength -- low in power loss.
Dust and Dirt cannot accumulate
on their original diamond hard
|
and super-smooth surface. There is no "glaze" to check
or crack.
Made in several styles and in
various sizes: antenna, lead-in, stand-off, bus-bars,
inductance shapes, bushings, rods and cylinders.
A treatise on the unique chemical,
physical and electrical properties of the special glasses
from which these high-test insulators are made will be
sent on request. Write for "PYREX Industrial
Glass Products."
