Black-Max® "Obround" 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.
