Pilot Tube & Accessories
Akkerman dual-wall tube design allows trenchless contractors to install pilot tubes with pinpoint accuracy while reducing pressures necessary for longer installations. The annular space between the inner and outer tube is used for a conduit for lubricants or compressed air for rock hammer operation. The inner tube is treated for corrosion resistance and sealed for a clear site path to the target located directly behind the steering head.
Pilot tube accessory kits are included in every Akkerman GBM hydraulic power pack. These kits include items such as a steering head kit for multiple ground conditions, nitrogen purge kit for extended drive lengths, reception shaft hydraulic break-out tool, and many other items that are useful for successful installations.
Pilot tubes are sold in easy to manage racks containing 30-lf or 100-lf racks.
