Dimensions per ANSI B16.5 standard for pipe flanges and gaskets.
Dimensional Tolerances (unless otherwise stated) through 1" @ +- 132", from 1" through 12" @ +- 116", from 12" through 24" @+- 332", and over 24" @ +- 14".
"New Style" Flange Gasket dimensions are listed, but "Old Style" are also available. The only difference is that "New Style" have a slightly enlarged ID on 12" and below so as not to obstruct flow when compressed (bolt holescircles unaffected).
Standard Pipe Flange Gaskets are SBR Rubber (a.k.a. Red Rubber), but Neoprene, EPDM, Buna N, Silicone, Viton (Fluoroelastomer), and other rubber compounds are also available upon request.
