This o-ring is supplied in red Silicone 70 Shore A with an inside diameter of 55 mm (2.165 in), a cross section of 2.5 mm (0.098 in), and an outside diameter of 60 mm (2.36 in), catalogued under part number SFDA2.5X55. It 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.
It resists many oxidizing chemicals, ozone and UV exposure, and extreme heat and cold. Silicone is widely chosen for flexibility that holds at very low temperatures, physiological inertness and low toxicity. Continuous operating temperature is published at -80°F (-62.2°C) to 450°F (232.2°C).
The compound meets FDA requirements for food contact, is metal detectable for HACCP and foreign-body control programs. It sees regular use in medical devices, electronics and electrical enclosures, and pharmaceutical manufacturing.
Stocked as SFDA2.5X55 and sold individually. Unit weight is approximately 0.0064 g. Check the compound against your process media, pressure and temperature before committing to a design.
