The material holds up against many oxidizing chemicals, weathering, and dry heat. That behavior comes from the compound itself: Silicone is known for flexibility that holds at very low temperatures and an exceptionally wide service temperature range. Service temperature is rated from -80°F (-62.2°C) through 450°F (232.2°C). It should not be specified for service in concentrated acids or hydrocarbon fuels and oils.
This o-ring meets FDA requirements for food contact. Maintenance and OEM teams specify it across food and beverage processing, medical devices, and electronics and electrical enclosures.
S2X35 ships individually. Unit weight is approximately 0.51 g. Review your operating media and conditions against this specification before installation. 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.
