It compresses into its gland to block fluid or gas migration across a joint.
As a material, Silicone is valued for very good compression set resistance across its range and an exceptionally wide service temperature range. The compound resists ozone and UV exposure, extreme heat and cold, and many oxidizing chemicals. Rated temperature range runs from -80°F (-62.2°C) to 450°F (232.2°C) in continuous service. Applications involving steam above its rated range or concentrated acids call for a different compound.
This item is metal detectable for HACCP and foreign-body control programs. Common environments for this compound include ovens and heated equipment, medical devices, and pharmaceutical manufacturing.
Order part number S70MD359, sold individually. Nominal inside diameter is listed as 5 3/4 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
