Boiler Gaskets - Topog-E, Black Max, Blue Max, Spiral Max Topog-E Manhole & Handhole Gaskets Topog-E Series 450 "Elliptical" Boiler Gaskets
Topog-E Series 450 "Elliptical" boiler gaskets are made from a special formula glass/elastomer-impregnated tacky cloth. The gaskets have their sizes clearly marked for easy installation. These super-strong gaskets resist splitting due to over-tightening flange surfaces.
Topog-E Series 450 "Elliptical" boiler gaskets will give you all of the advantages of an asbestos gasket without the health risks. Blue-Max® gaskets are manufactured from a proprietary tacky cloth of glass synthetic fibers and brass wire, and impregnated with a blue elastomer compound.
GASKETS ARE 1/4" NOMINAL THICKNESS
Topog-E Series 450 Gasket Key Benefits:
Zero Leakage Under Pressure: Tests by major boiler manufacturers confirm that Topog-E Series 450 gaskets seal with zero leakage on steam to 450 psi and on cold-water hydro tests up to 1500 psi and withstand working temperatures up to 500℉
Easily Removed: Removal is easy and requires no scraping, chiseling or grinding.
Sizes Clearly Marked: Each Topog-E Series 450 gasket is permanently marked with its size.
Easy Problem Free Installation: The gasket naturally lays flat on the flange and requires no special installation tools, procedures or training.
Interchangeable Sizes: Corresponding OB round and oval sizes are interchangeable.
Maximum Sealing on Rough Surfaces
Chemical Resistant: The proprietary Teflon wrap is resistant to the chemicals used in treating boiler water, so gaskets will last longer.
Extended Shelf Life: A Topog-E Series 450 Gasket won't dry out or lose its strength while in sits on the shelf.
