Ordered as SFDA3X45, this is a red Silicone 70 Shore A O-Ring measuring an inside diameter of 45 mm (1.772 in), a cross section of 3 mm (0.118 in), and an outside diameter of 51 mm (2.01 in). The o-ring creates a positive seal at flange, piston and rod interfaces without added hardware. Additional detail on this item: FDA Compliant TO 21CFR Sec 177-2600, Metric O-RING.

It resists weathering, dry heat, and ozone and UV exposure. That behavior comes from the compound itself: Silicone is specified for an exceptionally wide service temperature range, physiological inertness and low toxicity. Rated temperature range runs from -80°F (-62.2°C) to 450°F (232.2°C) in continuous service. It should not be specified for service in concentrated acids or abrasive dynamic service.

This o-ring meets FDA requirements for food contact under 21 CFR 177.2600. Maintenance and OEM teams specify it across sanitary process lines, food and beverage processing, and pharmaceutical manufacturing.

Order part number SFDA3X45, sold individually. Unit weight is approximately 0.0064 g. As always, verify media compatibility and operating conditions against the requirements of your specific application.
