Continuous operating temperature is published at -80°F (-62.2°C) to 450°F (232.2°C). Verify compatibility before use with steam above its rated range or hydrocarbon fuels and oils.

This item is metal detectable for HACCP and foreign-body control programs. Common environments for this compound include food and beverage processing, electronics and electrical enclosures, and sanitary process lines.

Reference part number S70MD256 when ordering; the item is sold individually. Nominal inside diameter is listed as 5 3/4 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
