-249 RED SILICONE 70D FDA O-RING

APG stocks the S70FDA249, an AS568-249 red Silicone 70 Shore A O-Ring with an inside diameter of 4.859 in (123.42 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 5.137 in (130.48 mm). An o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

As a material, Silicone is specified for excellent electrical insulating properties and an exceptionally wide service temperature range. The compound resists dry heat, many oxidizing chemicals, and ozone and UV exposure. The material carries a published service range of -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.

S70FDA249 ships individually. Unit weight is approximately 5.67 g. As always, verify media compatibility and operating conditions against the requirements of your specific application.
