This is an elastomer Viton O-Ring for a grooved ASA 4.25 / ANSI 1 flange. The O-ring's width is 0.120 in. and its I.D. is 1.875 in. Used to mate an ASA 4.25 / ANSI 1 grooved flange with an ASA 4.25 / ANSI 1 smooth (non-grooved) flange. Viton® (FKM) is the most popular O-ring seal material used in rough vacuum systems and is rated for high vacuum to 1 x 10-8 Torr. Viton is chemical and compression set resistant and has a working temperature range (continuous) of approximately -20°C to +150°C (-4°F to +300°F). The permeability of Viton does not allow it to be used for ultra-high vacuum applications. ASA flanges are available with a smooth or grooved face, rotatable or non-rotatable, bored or non-bored, and are named for the outer diameter of the flange, from 4.25 to 19 inches. The ANSI name for the same flange size corresponds to the nominal tubing size that can be welded to it, and ranges from 1 to 12 inches in diameter.
