Extension Pipe is the Chicago Pneumatic service part carried under part number P071147, also listed as 3310104444. This is part of the supply line to the tamper, and it is replaced on condition: abrasion, cover damage, or a fitting that will not seal.
Crowder’s breakdowns list this part on the CP 0003 Backfill Tamper and CP 0004 Backfill Tamper. That machine is the CP 0003 Pneumatic Backfill Tamper if you are pricing a replacement rather than a repair. Worth matching the reference number on the diagram against your own machine before you order the same part number can sit in more than one position.
