  • PTFE material resists chemicals across -450 to 500 Degrees F
  • Full-face design covers 12-inch ANSI Class 150 flanges completely
  • 12 bolt holes at 1-inch diameter ensure secure alignment
  • 1/16-inch thickness provides reliable sealing for 19-inch outside diameter
  • White PTFE construction contains no insert or binder material

Industrial PTFE Gasket for 12-inch Piping

This full-face flange gasket is manufactured from PTFE and rated for ANSI Class 150 service. It suits maintenance teams and plant engineers who need a chemically inert seal for 12-inch pipework. The material withstands temperatures from -450 to 500 degrees Fahrenheit.

Replaces Deteriorated Soft-Cut or Rubber Seals

The gasket upgrades joints that currently use non-PTFE materials and suffer from chemical attack or cold-flow creep. The step is justified when the process media attacks elastomers or when operating temperatures exceed the limits of conventional fibre gaskets.

Fits 12-inch Class 150 Flanges with 12 Bolt Holes

The 19-inch outside diameter and 1-inch bolt holes align with the standard drilling pattern. A 1/16-inch thickness compresses under bolt load to fill flange imperfections without requiring additional sealant. The white PTFE construction is not metal-detectable.

Questions about this item

What flange dimensions and bolt pattern does the 12 in full-face PTFE gasket require?

It matches ANSI Class 150 with a 19 in outside diameter, 12 3/4 in inside diameter, twelve 1 in bolt holes on a standard bolt circle.

Which installation step is most often missed with this 1/16 in PTFE sheet gasket?

Torque the bolts in a cross-pattern sequence to the flange-spec value; uneven loading splits the thin PTFE and causes leaks.

When should this PTFE flange gasket be replaced in service?

Replace at every flange break or if the faces show creep, cold-flow deformation, or chemical attack beyond the -450 to 500 °F rating.
