DUOSEAL® Watertight Access Assembly
Watertight manhole cover and frame prevents inflow and overflow
Prevent discharges, protect against inflow, and suppress odors.
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.
