T-Handle Washer Gasket (Model #TH430HDL-GSK)

T-Handle Washer Gasket (Model #TH430HDL-GSK)

The Model #TH430HDL-GSK is a commercial-grade elastomer washer seal engineered specifically for quick-acting flush-deck T-handle manholes. Installed tightly around the rotating handle stem, this component functions as the primary localized moisture barrier, preventing water, deck wash, and salt spray from migrating down into the handle sleeve bore. Fabricated from a high-density, oil-resistant rubber compound, it retains its sealing elasticity under heavy compression and constant environmental exposure.

Key Features

  • Oil & Fuel Resistant Compound: Formulated to withstand constant exposure to marine diesel, lubricants, and harsh saltwater without swelling or rotting.
  • Excellent Compression Set: Maintains an airtight, watertight seal under cyclic compression forces as the T-handle is tightened and released.
  • UV & Ozone Protection: Specially stabilized to resist cracking, dry rot, and degradation caused by direct sunlight exposure on open commercial vessel decks.
