Ordered as SFDA1.5X12, this is a red Silicone 70 Shore A O-Ring with an inside diameter of 12 mm (0.472 in), a cross section of 1.5 mm (0.059 in), and an outside diameter of 15 mm (0.59 in). The o-ring remains the most cost-effective sealing element available for pressurized assemblies. Source specification: FDA Compliant TO 21CFR Sec 177-2600, Metric O-RING, JIS S12.5.
Expect good resistance to dry heat, many oxidizing chemicals, and weathering. That behavior comes from the compound itself: Silicone delivers an exceptionally wide service temperature range, physiological inertness and low toxicity. Continuous operating temperature is published at -80°F (-62.2°C) to 450°F (232.2°C). It should not be specified for service in steam above its rated range or abrasive dynamic service.
The compound meets FDA requirements for food contact under 21 CFR 177.2600. It sees regular use in medical devices, food and beverage processing, and pharmaceutical manufacturing.
This item is sold individually under part number SFDA1.5X12. Unit weight is approximately 0.0064 g. Application requirements vary, so validate compatibility with your process conditions prior to installation.
