Silicone is specified here for exceptionally wide service temperature range and flexibility that holds at very low temperatures. It resists weathering, extreme heat and cold, and many oxidizing chemicals. Continuous operating temperature is published at -80°F (-62.2°C) to 450°F (232.2°C). It is not the right choice where abrasive dynamic service or concentrated acids are present.

This item meets FDA requirements for food contact. Maintenance and OEM teams specify it across sanitary process lines, food and beverage processing, and medical devices.
