Full-Face Viton Gasket 3" Pipe

This Zoro Select full-face flange gasket uses FKM material for chemical resistance in piping systems. It fits 3-inch pipe size with an inside diameter of 3-1/2 inches and an outside diameter of 8-1/4 inches. The gasket is 1/16 inch thick and rated for ANSI Class 300 flanges.

For Chemical Process Sealing

Suitable for engineers specifying seals in aggressive fluid service between -20 and 450 degrees Fahrenheit. The eight bolt holes at 7/8 inch diameter align with standard Class 300 drilling. Buyers needing a different temperature range, pressure class, or non-FKM material should select another gasket type.

FKM Material Handles 450 Degrees F

The FKM construction provides the high-temperature limit of 450 degrees F and broad chemical compatibility. This single specification determines if the gasket survives the intended process media and thermal cycling. Verify the operating envelope against your system requirements before ordering.

Questions about this item

How hot can the Viton material get before it fails?

The gasket is rated for a maximum operating temperature of 450 degrees Fahrenheit, so sustained heat above that limit will cause material breakdown.

Will the bolts and flange surfaces stay cool enough for the gasket to survive continuous duty?

The gasket itself handles up to 450 degrees Fahrenheit and down to minus 20 degrees Fahrenheit, but heat transfer depends on the piping system and media temperature.

Which flange standard and bolt pattern does this 3-inch gasket match?

It is cut for ANSI Class 300 flanges with an 8 1/4-inch outside diameter, 3 1/2-inch inside diameter, eight bolt holes of 7/8-inch diameter.
