8" Aluminum Hydro Excavation Dig Tube, Flat Flange x Poly Cuff

The 8" aluminum hydrovac dig tube is the full-size version: an 8" flat flange tube with a non-conductive poly cuff, for trucks running 8" suction.

It adds a 72" length the 6" tube doesn't offer, so you can match the length of the 8" extensions. The cuff bolts on with four supplied nuts and bolts through a 4 x 1/4" pattern.

8" Aluminum Hydro Excavation Dig Tube FAQ

How do I know which connection my truck uses?

Look at the end of your current tube: flat flange (Vactor and Vac-Con style), Bandlock or Ringlock. Match the connection and the diameter.

Aluminum or HDPE?

HDPE tubes are non-conductive and resist corrosion and abrasion. Aluminum dig tubes come with a non-conductive poly cuff on the digging end, and aluminum extensions are flanged both ends.
