Topog-E Manhole & Handhole Gaskets

Topog-E® Series 180 EPDM gaskets are engineered for reliable sealing in boiler handhole and manhole applications, as well as other pressure vessels with inspection openings. Designed to handle demanding steam conditions, they are commonly used at pressures up to 180 PSI and temperatures up to 380°F, while also performing well in water, condensate, and air systems. 

These molded rubber gaskets are formulated to provide excellent resistance to steam, hot water, and common water treatment chemicals, making them a durable and cost-effective solution across a wide range of industrial applications. 

One of the key advantages of Topog-E gaskets is their ease of installation and removal. The material naturally conforms to sealing surfaces without the need for adhesives, helping ensure a tight, leak-free seal—even on slightly worn or uneven seating areas. This also allows for clean removal during maintenance, reducing downtime and simplifying service. 

With over 40 years of proven performance in boiler systems worldwide, Topog-E Series 180 gaskets are available in a wide range of standard sizes and shapes, with custom options available to fit virtually any application. 

Designed for consistency, durability, and ease of use, these gaskets remain a trusted choice for maintaining proper sealing, preventing leaks, and supporting long-term boiler efficiency.
