1" Wide x 1/16" Thick SI Header Wrap, 50′ spool


SI Insultherm™Header Wrap is extremely high temperature resistant. Made from woven texturized amorphous silica filament yarn. Due to the yarn's texturization, it can withstand temperatures up to 2000° F providing great insulating values. Header Wrap SI is not made from leached fiberglas, which makes it a much more wear-resitant finished product.


    Resitant to high temperatue; withstands heat up to 2000°F.
    Resists Gasoline and Engine Chemicals.
    Reduces under hood temperature by approximately 70%Increases.
