EPDM Rubber Boiler Gaskets, Plates & Fiber Blankets | Boiler Supplies Black Max Boiler Handhole & Manhole Gaskets Black Max "Obround" Boiler Handhole & Manhole Gaskets
Compared to spiral wound gaskets, Black-Max® seals better with our Exfoliated Graphite and has much better recovery properties.The steam boiler market makes extreme demands on gaskets
Black-Max® Series 2000 gaskets are specifically designed and fabricated to provide the superior performance users of
Black-Max® gaskets have come to expect – but at higher operating pressures and temperatures. These branded, engineered gaskets provide a cost-effective, reliable, and easy to use alternative to tacky-cloth, spiral wound and expanded PTFE gaskets.
BLACK-MAX® GASKETS
Ideal Applications for Black-Max®
Steam pressure Vessels - Liquid Treatment Vessels
Hot Water Heaters - Compressed air Tanks
De-mineralizers - Dryer cans in paper mills
Steam humidifers - Water towers
Water purifiers - Water softeners
Make-up tanks - De-aerators
Zero Leakage Under Pressure - Tests by major boiler manufacturers confirm that Black-Max® gaskets seal- with zero leakage-on steam to 450 psi and on cold-water hydro tests up to 1500 psi and Black-Max® withstands working temperatures up to 500 deg Fahrenheit. Rubber gaskets can't withstand that kind of pressure and heat.
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 1,200°F. Rubber gaskets can’t withstand that kind of pressure and heat. Easy Removal. Removal is easy and requires no scraping, chiseling or grinding - resulting in lower maintenance costs and less downtime.
Clearly 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. The proprietary graphite used to manufacture Black-Max® is chemically inert (pH 0 -14) and resistant to chemicals used in treating boiler water.
