DUOSEAL® Watertight Access Assembly
Watertight manhole cover and frame prevents inflow and overflow
Prevent discharges, protect against inflow, and suppress odors with DUOSEAL® watertight access assembly.
The DUOSEAL access assembly is ideal for flood prone areas or to prevent unwanted fluids from overflowing due to a surcharge in the system.
The bolted, dual-gasket design creates a watertight barrier to contain manhole structures and prevent inflow or overflow. The assembly has been tested to EJ Watertight Level 8 (L8), meaning it can withstand 3 1/2 atmospheres of pressure (51.45 psi), which is the equivalent of having approximately 118 ft of water on top of the manhole assembly.
