Topog-e Gaskets for Handhole and Manhole Plates

Topog-e Series 180 gaskets are quick and easy to install. They conform to the mating surfaces and need no adhesive or additional material. When servicing, they are simple to remove, and peel away easily and cleanly. Using Topog-E Series 180 gaskets can prolong boiler life, avoiding seepage and corrosion, and reduces boiler down-time. They help you look after one of your most important assets – the boiler itself. Topog-e boiler gaskets stop leaks and end corrosion around boiler handholes and boiler manholes of steam and hot water boilers, air tanks, and water heaters. Engineered to hold up to 385°F (195C) wet heat and 185 PSIG (13 BAR), Topog-e boiler gaskets can withstand even the toughest applications.
