The o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.
Silicone is specified here for excellent electrical insulating properties and exceptionally wide service temperature range. Expect good resistance to many oxidizing chemicals, dry heat, and weathering. Continuous operating temperature is published at -80°F (-62.2°C) to 450°F (232.2°C). Verify compatibility before use with concentrated acids or steam above its rated range.
The compound is metal detectable for HACCP and foreign-body control programs. Maintenance and OEM teams specify it across sanitary process lines, ovens and heated equipment, and medical devices.
Stocked as S70MD342 and sold individually. Nominal inside diameter is listed as 3 5/8 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation. For a size or compound outside the standard catalog, APG can quote from a print or sample.
