It compresses into its gland to block fluid or gas migration across a joint.
It resists ozone and UV exposure, weathering, and dry heat. Silicone is known for an exceptionally wide service temperature range and flexibility that holds at very low temperatures. 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.
The compound is metal detectable for HACCP and foreign-body control programs. Typical settings include ovens and heated equipment, food and beverage processing, and electronics and electrical enclosures.
Stocked as S70MD143 and sold individually. Nominal inside diameter is listed as 2 7/16 inch. Check the compound against your process media, pressure and temperature before committing to a design. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
