Avoid chemical processes used for cleaning, electropolishing and passivation that will remove plating. If the plating is damaged or removed, thread galling will occur, damaging fitting components and preventing a proper seal. imensions imensions are in inches and (mm) for reference only, subject to change. dimension references the smallest nominal inside diameter of the part. Ratings Ratings are based upon tests conducted using VR assemblies. All ratings comply with calculations per ANSI ode for iping o determine pressure ratings in accordance with ANSI 31.1, multiply psig rating by Ratings determined at ambient temperature. emperature Ratings omponents ittings Gaskets emperature Material 316 stainless steel L stainless steel LV stainless steel stainless steel nickel copper esting he VR assembly with silver plating has been helium leak tested to a rate of std cm 3 /s and the unplated gasket to a rate of std cm 3 /s without leakage. Ultra-igh-urity A variety of VR face seal glands and bodies are available with controlled surface finishes, electropolished, and specially cleaned to meet Ultra-igh-urity system requirements. or more information see Swagelok Specification S-01.
