Full-Face Flange Gasket 3/4" Pipe

This full-face flange gasket fits 3/4-inch pipe and ANSI Class 150 flanges. It uses FKM material with a black finish and four 5/8-inch bolt holes. The gasket measures 1-1/16-inch inside diameter by 3-7/8-inch outside diameter at 1/8-inch thickness. It is sold new without mounting hardware.

Chemical piping systems needing FKM resistance

Suited for installations handling chemicals between -20 and 450 degrees Fahrenheit. Buyers who need a metal-detectable gasket or a different hardness rating should look at other options. The product carries a California Proposition 65 notice for reproductive-harm chemicals.

FKM material for chemical service

The gasket material is FKM, which determines compatibility with the fluids in your system. Verify that FKM suits the specific chemicals, temperatures and pressures before purchasing. No other specification overrides this material choice.

Questions about this item

Does the FKM gasket handle continuous heat up to 450 Degrees F without hardening?

The gasket is rated for a maximum operating temperature of 450 Degrees F and a minimum of -20 Degrees F, so it remains flexible across that range.

Which flange standard and bolt pattern does the 3/4 in gasket match?

It fits ANSI Class 150 flanges with a 3 7/8 in outside diameter, four bolt holes of 5/8 in diameter, and a 1 1/16 in inside diameter.

Will this full-face gasket seal against the raised-face flanges already on my chemical line?

The gasket covers the entire flange face including bolt holes, so it seals on both raised-face and flat-face flanges when bolted to the ANSI Class 150 pattern.
