Corrugated Metal Core gaskets faced with graphite supplied by Sterling Seal & Supply combines the sealing properties of the Flexible Graphite with the extrusion resistance of the corrugated metal core. The main advantage for using a metal core gaskets faced with flexible graphite is that it provides an extremely effective seal under low bolt loads. This makes the gasket ideal for applications where the available loading is determined to be low and unsuitable for spiral wound or other type of gasket requiring high seating stress. It is designed to maintain a positive seal through thermal cycling and shock load conditions. These gaskets can be used in a wide variety of media, i.e. a pH range varying from 0-14. Standard gaskets are available in accordance with ASME B16.21 (1/2” – 24”) , EN12560-1 as well as EN1514-1 (DN10- DN600). Standard thickness is 1,6 mm (1/16”)en 3,2 mm (1/8”).Non-standard, or special gaskets, can be manufactured according to particular customer drawings, or by given sizes.
