"Say Goodbye to Spiral-Wound Gaskets"
Compared to spiral-wound gaskets, Black-Max® gaskets seal better and have much better recovery properties. While spiral-wound 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, insuring 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. Stocked in popular sizes and can be produced to fit your plants individual needs as required. Removal is easy and requires no scraping, chiseling or grinding - lowering your downtime and reducing maintenance costs
