Black-Max Boiler Manhole & Handhole Gaskets / Joints - Non Asbestos
Key Black-Max Advantages
No leakage under pressure. Even the slightest leakage will increase maintenance requirements and reduce your product's life. Field tests by major end users confirm that Black-Max gaskets seal with zero leakage in steam and in cold water hydro tests. Black-Max withstands working steam temperatures up to 1200°F, Rubber gaskets can't withstand that kind of pressure and heat.
Easy removal. Removal is easy and requires no scraping, chiseling or grinding - so you'll experience lower maintenance costs and less downtime.
Easily Marked Sizes. Each gasket's size is permanently marked, so you'll know immediately that you have the one you need.
Maximum Sealing on Rough Surfaces. 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 surface topography and maintain the tightest possible seal.
Chemical Resistance. The proprietary graphite used to manufacture Black-Max is chemically inert
(pH 0-14) and resistant to chemicals used in treating boiler water.
Extended Sheld Life. Black-Max gaskets wont dry out or lose their strength while sitting on the shelf.
Ideal Applications for Black-Max Gaskets
- Steam pressure vessels
- Hot water heaters
- De-mineralizers
- Steam humidifiers
- Water purifiers
- Refrigeration Units
- Filtering units
- Liquid treatment vessels
- Compressed air tanks
- Dryer cans in paper mills
- Water towers
- Water softeners
- De-aerators
- Make-Up tanks
