Product Overview
Description:
These gaskets are comprised of Flexible Graphite, manufactured from exfoliated graphite flakes, compressed into a foil through a precise calendering process which is then reinforced with a 316SS tanged core. Through this calendering process, the graphite flakes are mechanically entwined without using binders, fibers or other additives.
Flexible graphite gaskets have very low creep relaxation, making re-torquing rarely required. They conform easily to irregular flange faces and sealing surfaces, ensuring a tight seal on both coarse and smooth surfaces.
When it comes to sealing flanges, whether raised or flat face flanges, there are two type of gasket shapes - Ring Gaskets and Full Face Gaskets. Full Face Gaskets are similar to Ring gaskets, as they too are used to seal raised flanges, however Full Face are designed with a specified number of holes for securing bolts to pass through, thus making alignment easier and clamping easier. Full Face gaskets also have the added benefit of filling the hap between the bolting surfaces. The disadvantage is that the joint must be completely dissembled for installation.
Applications:
Due to its excellent resistance to extreme temperatures, heat, fire, aggressive chemicals and corrosion, Flexible graphite gaskets are highly versatile and one of the most universally applicable sealing solutions. This gasket material has an excellent resistance to chemical attacks from virtually all organic and inorganic fluids (excluding high-oxidizing acids). Flexible graphite gaskets are ideal within low bolt load applications, high temperature flanges and virtually any chemical applications. Please handle flexible graphite gaskets with care; some styles with inserts may be sharp on the sides.
Do Not Use Within:
These gaskets are not suitable with Glass-Lined, Aluminum or Bronze flanges.
