Protection tubes are stocked in multiples of 6 inches starting at 12 inches, although any length can be specified.
Richards metal thermocouple protection tubes are manufactured using our special processes to maximize the tube service life. This is
evident by our uniquely shaped, heavy mass tips which have been proven in the field for years. Prior to shipment, each tube goes through our
Hydro-Pneumatic testing to check for porosity.
