Boiler manway and handhole gaskets

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.

 

These gaskets conform to boiler mating surfaces, withstand full, continuous and cycling operating pressures and withstand water treatment chemicals and continuous exposure to ion and oxygen attack in hot air.

 

  • Service Summary

Steam Boilers up to 180 psi (12 bar) and 380F (193C) Water, condensate etc. Vessels: 200+ Psi (14 bar) and less than 300F (150C)

  • Material Description

Special proprietary rubber, composition black, 80-85 durometer

 

Topog-E Series 2000 Proprietary graphite construction offers exceptional thermal stability and chemical inertness, ensuring superior capability under simultaneous conditions of saturated and superheated steam.

Compressible enough to conform to even worn or pitted mating surfaces with less torque than spiral wound gaskets, these gaskets also have superior recovery characteristics.
