Application fit

This PTFE ring gasket is manufactured for two-inch piping systems that use ANSI Class 300 raised-face flanges. It provides a chemically resistant seal in process lines where aggressive media or wide temperature swings rule out conventional fibre or rubber materials.

Upgrade path

The gasket replaces worn or deteriorated flat gaskets on existing Class 300 flanges when leakage or permeation becomes an issue. Switching to PTFE is justified when the service sees temperatures between minus 450 degrees F and 500 degrees F or when the fluid attacks standard binder-based gaskets.

Installation checks

Verify that the flange faces are raised-face type and that the bolt circle matches the four and three-eighths inch outside diameter with a two and three-eighths inch bore. Confirm the one-eighth inch thickness suits the available bolt stretch and that no metal-detectable or x-ray-detectable requirement applies to the line.

Questions about this item

What flange class and bolt pattern does this 2-inch PTFE gasket match?

It is cut for ANSI Class 300 flanges with a 2 3/8-inch inside diameter and 4 3/8-inch outside diameter.

Which side faces the pipe when seating the raised-face PTFE ring?

Either flat face can contact the flange; just ensure the raised face seats fully before tightening bolts in a star pattern.

When should the PTFE ring be replaced in a 500 °F steam line?

Inspect at each shutdown; swap it if the white material shows creep, hardening or surface cuts from thermal cycling.
