Full Description
The IsoShield Subsea™ Gasket is 8mm thick, comprising of a steel core (commonly 316, Inconel 825 or 625) and a glass reinforced laminate facing and is designed with a tandem or Triple Seal arrangement. The inner seal is spring energized Teflon which is pressure activated and works well up to 10,000 psi pressure, the secondary seals are Viton O Rings which deforms well into any imperfections on the flange face. The secondary seal are by-directional ensuring an leak free seal from both internal and external pressure. Unlike RTJ gaskets these product do not rely on deformation and therefore hardness levels are not relevant.
