Buna-N Gasket for 15" x 23" Multi-Bolt Flush Manhole (Model #MB-G1523FLSH)

The Model #MB-G1523FLSH is a specialized replacement perimeter gasket engineered specifically for 15" x 23" elliptical multi-bolt flush manholes. Fabricated from high-density Buna-N Nitrile rubber, this heavy-duty molded seal is designed to drop securely into the recessed groove of flush-deck mounting frames. It provides exceptional resistance to compression flattening, keeping the hatch plate perfectly level with the surrounding deck plating while under severe heavy cargo loads and constant vehicular traffic.

Key Features

  • Flush-Profile Mechanical Integrity: Formulated to resist structural displacement and thinning when the hatch cover is subjected to high vertical shear and heavy wheel-load compression.
  • Excellent Petroleum & Fuel Resistance: Impervious to swelling, rotting, or mechanical breakdown when exposed to marine fuels, lubricants, ballast bilge water, and severe salt spray.
  • Seamless Loop Engineering: Factory-molded as a single continuous piece to eliminate vulnerable joint seams, guaranteeing zero-leakage performance under structural hull flexing.
