Basic design available in many variations for non-circular or irregular shapes. Constructed of soft, compressible filler, partly or totally encased in metal jacket.

Intended for narrow applications. Consists of a soft filler encased with metal on one face and both edges. This kind of construction lends itself to narrow-faced closures, since width diameter restrictions do not apply. Non-circular shapes available.

Perfect for applications which require maximum protection of filler material. Gasket also supplies extra support of flange at outer edge by addition of lapped-over jacket. Construction consists of soft filler fully encased in metal shell and top washer. Enclosed edges and additional protection of washer make #323 well-suited for non-circular applications. Added thickness of outer lap helps to avoid excessive distortion of light-weight flanges. Gasket comes in non-circular, irregular shapes.

Employs corrugated jacket for added resilience. Consists of soft filler fully enclosed in corrugated metal shell and top in case of leakage across inner edge. #326 is used for circular and moderately non-circular shapes in 3/8" and wider widths, such as valve bonnet ovals.

Intended for use when fully enclosed jacket is needed in narrower widths than are available in the plain, double-jacketed type. Minimum I.D., one inch. Made of a soft filler entirely encased by a single metal shell which overlaps on one face.

The perfect gasket for narrow circular uses that require a positive, unbroken metal gasket face across the full width. Typical applications: valve bonnets, sight glasses, vacuum seals. This type gasket is constructed by flanging a metal jacket over the inner edge and the two faces of a soft filler while outer edge is left exposed. Maximum width is restricted by the metal, diameter and gasket thickness.

For applications in which outer edge of gasket is exposed to the fluid pressure. Also used when a non-metallic gasket is required but mechanical reinforcement is desired around outer edge. Construction consists of a soft filler with metal jacket over outer edge and all or part of the two faces.
