METAL REINFORCED FIBER GASKET MATERIAL

COMMON APPLICATIONS
Catalytic Converter Gaskets, Exhaust Manifold Gaskets, EGR Gaskets, Heat Shield Applications, Diesel Exhaust Gaskets

TEMPERATURE RATING
1000 °C/1800 °F

GENERAL DESCRIPTION
Fiber gasket uses a 0.008” ETP (electrolytic tin plate) low carbon steel core. The core is then laminated on two sides with a facing composed of heat resistant vermiculite and ceramic fibers chemically bonded with an NBR binder. It is designed for hot gas applications where extreme heat is present.

The fiber facings are mechanically bonded without the use of any adhesives, providing stability and integrity even when exposed to high heat, scrubbing and vibration. Color is light brown.
