OMEGA®miniature and
standard protection tubes are
available in 316 stainless steel
and Inconel 600 nickel alloy.
Tubes are available either opened
at both ends or with one end
closed. Standard length available
from stock is 150 mm (6");
however, practically any length tube
is available on short delivery.
OMEGA’s protection tubes are
intended for use with OMEGA’s
fine or heavy gage thermocouples
and ceramic insulators, as well as
OMEGA’s standard thermocouples
made from OMEGACLAD
®
thermocouple wire. These items
are shown in Section A of this
catalog. Bare wire thermocouples
can be insulated using
OMEGATITE®ceramic insulators
as well as the insulators used in
replacement elements.
OMEGA’s protection tubes can be
conveniently secured into pipes,
vessels, and chambers
by using OMEGALOK
®
compression fittings.
