Even the slightest leakage is too much, as it increases SIZES\nmaintenance and reduces boiler life. Tests by major boiler manufacturers confirm that Topog-E® Series 450 gaskets are\nTopog-E® S-450 gaskets seal with zero leakage in steam to 450 psi and can withstand available in almost any shape or size.\nworking temperatures up to 500°F. As a standard, Topog-E® S-450 is\n provided in 1/4\" (6.4mm) thickness.\nEasily removed. Topog-E® S-450 gaskets will not stick to the plate after being in service. Other thicknesses are available\nRemoval is easy and requires no chiseling or buffing. This is important in reducing upon request.\nmaintenance costs and boiler downtime.\nEasy, problem-free installation. Topog-E® S-450 gaskets offer installation advantages\nover other types. Because of the material’s construction and strength, there is no danger\nof overtightening the gasket and cutting it in half. A Topog-E® S-450 gasket naturally lays\nflat on the flange, and requires no special installation tools, procedures or training. Simply\ninstall the gasket and crank it down.\nInterchangeable sizes. Corresponding obround and oval sizes are interchangeable, thanks\nto the unique properties of the material. It is not necessary to stock separate gaskets to\naccommodate slight size variations, and chances of a dangerous mismatch are reduced.\nMaximum sealing on rough surfaces. Rough and pitted surfaces on old or poorly maintained\nflanges pose no problem for a Topog-E® S-450 gasket. The material is resilient enough to\nconform perfectly to surface topography and maintain the tightest possible seal.\nChemical-resistance. The proprietary Teflon coating is resistant to the chemicals used in\ntreating boiler water, so gasket life will be longer.\nExtended shelf-life. A Topog-E® S-450 gasket won’t dry out or lose its strength while it sits\non the shelf.\n\n\n\n\n Topog-E, LLC · 1150 Guadalupe Drive · Cibolo, Texas 78108\n 918-587-6649 · info@topog-e.com · www.topog-e.com\n All information in this data sheet is based on data believed to be reliable; however, we make no guarantee or warranty of the performance\n of Topog-E® Series 450 gaskets.
