Boiler Gaskets - Topog-E, Black Max, Blue Max, Spiral Max White Max Boiler Gaskets Pure PTFE, FDA compliant White Max "Obround" Boiler Gaskets (Pure PTFE, FDA Compliant Gasket)
WHITE-MAX® obround gaskets are designed for boiler and tank inspection ports, providing reliable sealing with low stress and excellent dimensional stability. Made from 100% expanded PTFE, they are soft, highly compressible, and ideal for worn or uneven surfaces. These gaskets resist creep, maintain bolt torque, are FDA compliant, and offer long shelf life with no environmental degradation.
PLEASE NOTE: As part of a merger between WHITE-MAX and TOPOG-E, the WHITE-MAX name is being retired. It will eventually only be offered under the name TOPOG-E SERIES 3000. WHITE-MAX and TOPOG-E SERIES 3000 are the same gasket — the same PTFE material, same manufacturing, same performance. You may see either name used on packaging while the WHITE-MAX name is being phased out.
WHITE-MAX® (TOPOG-E Series 3000) Advantages:
High adaptability, suitable for flanges with corrosion and with uneven sealing surface
Pressure test and service with the same gasket
Very easy installation and removal
Anti-sticking material, low effort for surface cleaning when installing a new gasket
No embrittlement of the gasket in storage or in service
Pure PTFE, conforms to FDA standards
