-344 RED SILICONE 70D O-RING

S70344 is an AS568-344 red Silicone 70 Shore A O-Ring with an inside diameter of 3.85 in (97.79 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 4.27 in (108.46 mm). In service, this o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

The compound resists ozone and UV exposure, dry heat, and weathering. Silicone is known for an exceptionally wide service temperature range and very good compression set resistance across its range. Rated temperature range runs from -80°F (-62.2°C) to 450°F (232.2°C) in continuous service. Verify compatibility before use with steam above its rated range or concentrated acids.

Common environments for this compound include medical devices, sanitary process lines, and pharmaceutical manufacturing.

S70344 ships individually. Unit weight is approximately 9.944 g and nominal inside diameter is listed as 3 7/8 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
