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

Pipe-to-Manhole and Structure Connector Specification for Sanitary and Storm Sewer Applications:

All pipe-to-manhole and structure connections shall meet and or exceed ASTM C 923, Standard Specification for Resilient Connectors Between Reinforced Concrete Manholes, Structures, Pipes and laterals.

All mechanical devices, including castings, bolt assemblies, adjusters shall use non-magnetic 300 series stainless steel with no welds or rivets in its assemblies.

The installation of the connector shall be accomplished at one time and shall require no additional adjustments or installation at a later time to insure a watertight seal.

Take up clamps shall use non-magnetic 304 series stainless steel and be installed in the field using a T-Handle Torque wrench set to 60 inch-pounds and installation shall follow manufacturer’s instructions.

The connector shall be PSX: Direct Drive Nitrile and PSX: Nylo Drive Nitrile as manufactured by PressSeal Corporation of Fort Wayne, IN or approved equal.
