Topog-E Series 450 boiler gaskets will give you all of the advantages of an asbestos gasket without the health risks. Topog-E Series 450 gaskets are manufactured from a proprietary tacky cloth of glass synthetic fibers and brass wire and impregnated with a blue elastomer compound.
Key Benefits:
- Zero Leakage Under Pressure: Even the slightest leakage is too much, as it increases maintenance and reduces boiler life. 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 Topog-E Series 450 gaskets withstand working temperatures up to 500 degrees Fahrenheit. Rubber gaskets simply can’t withstand that kind of pressure and heat.
- Easily Removed: Removal is easy and requires no scraping, chiseling or grinding. This is important in reducing maintenance costs and downtime. Sizes Clearly Marked: Each Topog-E Series 450 gasket is permanently marked with its size, so you’ll know immediately that you have the appropriate one.
- Easy Problem-Free Installation: Topog-E Series 450 gaskets offer installation advantages over other types. Because of the material's construction and strength, there is no danger of over-tightening the gasket and cutting it in half. A Topog-E Series 450 gasket naturally lays flat on the flange and requires no special installation tools, procedures, or training. Simply install the gasket and crank it down. Refer to Step #4 on the Installation Instructions.
- Interchangeable Sizes: Corresponding OB round and oval sizes are interchangeable, thanks to the unique properties of the material. It is not necessary to stock separate gaskets to accommodate slight size variations and chances of a dangerous mismatch are thereby reduced.
- Maximum Sealing on Rough Surfaces: Rough and pitted surfaces on old or poorly maintained flanges pose no problem for a Topog-E Series 450 gasket. The material is resilient enough to conform perfectly to surface topography and maintain the tightest possible seal.
- 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.
