Zoro Select PTFE Flange Gasket 3 in

This full-face gasket fits 3 inch pipe flanges rated for ANSI class 150. It is made from white PTFE with no insert or binder material. The gasket suits industrial piping systems that require chemical resistance across a wide temperature range.

Installation fits standard four-hole pattern

The gasket has an inside diameter of 3 1/2 inches and an outside diameter of 7 1/2 inches. Four bolt holes at 3/4 inch diameter align with class 150 flanges. Misalignment or uneven bolt torque can cause leaks because PTFE cold-flows under sustained load.

PTFE temperature range and pressure class

The material withstands continuous temperatures from minus 450 to 500 degrees Fahrenheit. The ANSI class 150 rating defines the maximum pressure at temperature for the flange pair, not the gasket alone. Buyers needing higher pressure classes or metal-detectable gaskets must select a different product.

Questions about this item

How can I verify the gasket is sealing correctly after installation?

After torquing the four 3/4 in bolt holes to specification, pressurise the line and check for leaks; the PTFE material should hold from -450 °F up to 500 °F without weeping.

What comes in the box and what must I supply myself?

The package contains only the white full-face PTFE gasket with 3 1/2 in inside diameter and 7 1/2 in outside diameter; bolts, nuts and any lubricant are not included.

Which size should I choose for a 3 in ANSI Class 150 flange?

This BULK-FG-1173 gasket matches 3 in pipe, Class 150 flanges with four bolt holes of 3/4 in diameter and 1/8 in thickness.
