Nitrile pipe to manhole connectors offer the added ability to resist common underground contaminants including hydrocarbons and many mixed chemistries.

Whether you core or cast your holes, PSX: Direct Drive Nitrile fits right into your production methods, ready to seal your toughest applications every time.

How It Works

  • The connector fits into a cast or cored hole.
  • A power sleeve made from tempered series 304 stainless steel expands with a certified installation wrench.
  • Take-up clamps made from series 304 stainless steel with quick adjusting screws secure the connector to the pipe.

Why It's Better

  • Nitrile rubber resists most chemicals and hydrocarbons found in effluent and soils.
  • Safely install from outside of the manhole preventing falls from crawling down into structures.
  • All stainless-steel components with no welds or rivets creating a stronger product.
  • Precision molding provides accurate compensation for hole size variations.
  • Contains chemically resistant stainless steel.
  • Contractor can save time and money by backfilling immediately.

Where To Use

  • Manholes
  • Wet wells
  • Square pump and lift stations
  • Stormwater structures
  • On-site treatment structures
  • Junction chambers
  • Grease interceptors
  • Vaults
