Product Overview
Tolerances
The diameter and "out of roundness" of OMEGA's insulators is plus or minus 5% or ±0.015", whichever is greater. The straightness is at least 1/32 inch for each six-inch length. The following table lists the maximum recommended wire diameters which should be used with six-inch sections. Closer tolerances are permissible with shorter sections, but the minimum clearance tolerance is ±5% or 0.015 inch, whichever is greater.
OMEGATITE™ 450
This is an impervious, recrystallized, pure alumina ceramic containing over 99.8% Al2O3. It has the most superior gas and vacuum tightness and electrical insulating properties at elevated temperatures. It is non-reactive and recommended for use with platinum, as well as tungsten and molybdenum thermocouple alloys. The maximum service temperature is 1900°C (3450°F).
OMEGATITE™ 350
This is an impervious, recrystallized pure alumina ceramic containing over 99% Al2O3. It has superior gas and vacuum tightness and electrical insulating properties at elevated temperatures. It is non-reactive and compatible with tungsten and molybdenum thermocouple alloys. The maximum service temperature is 1900°C (3450°F).
OMEGATITE™ 200
This material is recommended for most thermocouple applications. It consists of a mullite type ceramic capable of withstanding temperatures up to 1650°C (3000°F).

Not Good - Undersized
Bought for insulating a thermocouple. Good material for the price. However, when trying to place thermocouples, we found (through measurements with plug gauges) that these were undersized. Would not buy again.

Excellent high temp TC insulators
I have used this product in the lab for years in a high temp environment reaching more than 1500 C. Excellent product.

NO suggestions on how to cut this
I wrote an email for help cutting these off and got unreasonable answers.
I recommend you sell the dremmel tool to use to cut these as part of your offerings.

Consistently good product.
Never had any problem using this tube for TC placement over many years of experience.
