Power Nozzle Neck Assembly - ProTeam Sierra (Black) G3 The bearing block sits atThis power nozzle neck assembly (part #105015, black) is a replacement for ProTeam Sierra power nozzles. The neck links the nozzle head to the wand and lets the head pivot for full cleaning coverage. Constant flexing wears the neck joint, and a cracked or stiff assembly limits how the head articulates or breaks the connection to the wand entirely. A fresh neck restores smooth pivoting and a secure wand link so the nozzle tracks the floor properly.
