IMPREG-TITE - IMPERVIOUS GRAPHITE THERMOWELLS Immunity or high resistance to: thermal shock, fatigue, age, and reasonable pressure changes or cycles. Corrosion proof when used with most corrosive materials except a few extreme oxidizing agents. Impregnation with modified resins provides high thermal conductivity, stability, and non-contamination of most process materials.   TYPE MARK I IPS THREAD MOUNTING   SIZE NO.
