WHITE-MAX® gaskets are specially designed for inspection ports of boilers and tanks. They provide reliable seal-ability with this low stress and exceptional dimension stability. This form of gasketing is processed by expanding 100% pure polytetrafluoroethylene (PTFE). The result is a bidirectional, soft, highly compressible gasket for longer life and trouble-free sealing. Its form-in-place versatility is perfect for sealing boilerplates that are worn, warped, or scored. The high compressibility of the WHITE-MAX® gasket enables it to effectively fill flange imperfections for a tight, leak-free seal. Unlike conventional PTFE which is prone to cold flow, WHITE-MAX® has good creep resistance and bolt torque retention properties.
