Overview:
  • The steam boiler market makes extreme demands on gaskets; Topog-E® molded rubber gaskets are specifically formulated to meet and exceed these demands and deliver industry-standard performance.
  • Topog-E® Series 180 gaskets have been refined through a series of over 600 research formulation tests to ensure that they are able to meet the exacting performance standards of the steam boiler industry.
Features:
  • Conform to the topography of the mating surfaces.
  • Withstand a boiler's full, continuous, and cycling operating pressures.
  • Withstand continuous exposure to water treatment chemicals.
  • Withstand continuous exposure to ion and oxygen attack in hot air.
  • Prevents all leakage.
  • Replace easily, without chiseling or buffing.
Material Description:
  • Special, Proprietary Rubber Composition, Black, 80-85 Durometer.
Service Summary:
  • Steam boilers: up to 180 psi (12 bar) and 380° F. (193° C)
  • Water, condensate, etc. vessels: 200+ psi (14 bar) and less than 300°F. (150°C)
Applications:
  • When used on steam pressure vessels Topog-E® Series 180 gaskets are typically used at operating pressures of up to 180 PSI (12 bar) and saturated steam temperatures up to 380° F. (193° C) for an average service life of one year. When used in other applications (e.g. condensate, water, and air vessels) Topog-E® Series 180 gaskets are sometimes used at pressures above 200 PSI (14 bar) where temperatures are typically more moderate (e.g. below 250°F./121°C.). When operating under less severe conditions (e.g. water applications at ambient temperatures) Topog-E® Series 180 gaskets can provide very long service lives.
  • Topog-E® Series 180 gaskets have been used successfully around the world for over forty years. In general, any type of industrial pressure vessel or tank that has inspection openings is a potential application where Topog-E® Series 180 gaskets can be used as a cost-effective sealing device. In addition to using them in steam pressure vessels, customers also use Topog-E® molded gaskets and sheet material with great success in many other applications:
    • Water softeners
    • Hot water heaters
    • Steam humidifiers and cookers
    • Water purifiers and demineralizes
    • Refrigeration units
    • Liquid treatment vessels
    • Carbon absorption and filtering vessels
