PSX:Wedge Drive’s patented stainless steel power sleeve and adjuster installs quickly and easily providing a flexible watertight seal for the most demanding applications. It is manufactured with no welds or rivets for unmatched structural integrity and durability.

If you need a manhole connector that resists common underground contaminants, the PSX: Direct Drive Nitrile would be the proper product.

How It Works

  • The connector fits into a cast or cored hole.
  • A power sleeve made from tempered series 300 stainless steel expands with a wrench.
  • Take-up clamps made from series 304 stainless steel with quick adjusting screws secure the connector to the pipe.

Why It's Better

  • With no welds or rivets, the PSX: Wedge Drive delivers uncompromised reliability.
  • The snap pins provide an extra layer of defense, safeguarding your assembly against failures in the field.
  • The heart of the PSX: Wedge Drive boasts a 300 series stainless steel power sleeve.
  • Greater Cored Hole Flexibility: This nearly 25% increase provides cored holes addition size flexibility, less QC headaches and better core bit life, saving money.

Where To Use

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