BLACK-MAX Hand Hole gaskets seal with zero leakage in steam and in cold-water hydro tests. BLACK-MAX withstands working steam temperatures up to 1,200°F. Rubber gaskets can't withstand that kind of pressure and heat.
Removal is easy and requires no scraping, chiseling or grinding - resulting in lower maintenance costs and less downtime.
Each gasket's size is permanently marked, so you'll know immediately that you have the one you need.
Rough and pitted surfaces on old or poorly maintained flanges pose no problem for BLACK-MAX gaskets: the material is resilient enough to conform perfectly to the surface topography and maintain the tightest seal.
The proprietary graphite used to manufacture BLACK-MAX is chemically inert (pH 0 -14) and resistant to chemicals used in treating boiler water.
