APG stocks the SFDA2X19, a red Silicone 70 Shore A O-Ring with an inside diameter of 19 mm (0.748 in), a cross section of 2 mm (0.079 in), and an outside diameter of 23 mm (0.91 in). An o-ring creates a positive seal at flange, piston and rod interfaces without added hardware. The catalog record notes: FDA Compliant TO 21CFR Sec 177-2600, Metric O-RING.
As a material, Silicone is valued for flexibility that holds at very low temperatures and an exceptionally wide service temperature range. Expect good resistance to ozone and UV exposure, extreme heat and cold, and many oxidizing chemicals. Published continuous service range is -80°F (-62.2°C) to 450°F (232.2°C). Exposure to steam above its rated range or concentrated acids will shorten service life.
The compound meets FDA requirements for food contact, is metal detectable for HACCP and foreign-body control programs. Maintenance and OEM teams specify it across electronics and electrical enclosures, ovens and heated equipment, and pharmaceutical manufacturing.
Reference part number SFDA2X19 when ordering; the item is sold individually. Unit weight is approximately 0.0064 g. Application requirements vary, so validate compatibility with your process conditions prior to installation.
