Zoro Select Viton Ring Gasket 6 in

This Zoro Select ring flange gasket is made from Viton FKM material for 6 inch pipe applications. It fits ANSI Class 150 raised face flanges with an inside diameter of 6 5/8 inches and an outside diameter of 8 3/4 inches. The gasket thickness is 1/8 inch and it contains no insert or binder material. It is supplied new in black colour.

Replaces worn Viton or softer rubber gaskets

Switch to this gasket when an existing seal has hardened, cracked or swollen from heat or chemical exposure. The FKM material handles a minimum operating temperature of -20 degrees F and a maximum operating temperature of 450 degrees F. The upgrade is worth it when the process fluid attacks standard elastomers or when service temperatures exceed the limits of nitrile or EPDM alternatives.

Limited to ANSI Class 150 raised face flanges

This ring gasket design only seals on raised face flanges rated for ANSI Class 150 service. It cannot be used on flat face, tongue and groove or higher pressure class flanges without changing the gasket type. The 1/8 inch thickness and fixed diameters mean it will not compensate for flange misalignment or surface damage beyond normal commercial tolerances.

Questions about this item

What are the inside and outside diameters of the 6 in Viton ring gasket?

The gasket has an inside diameter of 6 5/8 in and an outside diameter of 8 3/4 in for ANSI Class 150 flanges.

How should the raised-face Viton gasket be seated, and what common error causes leaks?

Center the gasket on the raised face before tightening bolts in a star pattern; skipping the star sequence leaves uneven compression and leaks.

When should this FKM gasket be replaced based on temperature exposure?

Replace it if the system exceeds 450 Degrees F or drops below -20 Degrees F, or after prolonged cycling near those limits.
