Compared to spiral wound gaskets, BLACK-MAX® gasket seal better and has much better recovery properties. And while spiral gaskets require near perfect conditions, BLACK-MAX® gaskets seal on rough, pitted surfaces under less compressive load. Black-Max® gaskets are made from multiple layers of foil-reinforced, exfoliated graphite and 316 stainless steel, ensuring gasket stability. The temperature range of the components and the recovery at broad temperature ranges (-400 to 1,200ºF Steam) allow you to use them in virtually any situation, in environments from cryogenic to steam.
