Part 100100 is ProTeam's compression ring for its aluminum two-piece wands, the collar that clamps the upper and lower wand sections together and keeps that joint tight and sealed while the wand is worked back and forth all shift. It ships as a bare ring rather than as part of a larger kit, for shops that already know which wand needs it.Compression rings are inexpensive, and that is exactly why they are worth replacing on their own rather than as an excuse to buy a whole new assembly. A ring that has flattened, cracked, or lost its grip lets air leak past the joint it was sealing, and a leak in the airflow path shows up as weaker suction at the tool end even when the motor and filters are in good shape. Because the leak is small, it is easy to mistake for a filter or motor problem until the joint itself is actually checked.Parts listings match this ring to ProTeam's aluminum wand assemblies, including wand part numbers 10002, 100104, 101338, 106290, and 106293, which ProTeam runs across its backpack platforms. Check the ring against the wand it is replacing, or against your machine's part diagram, before ordering to confirm it is the correct size.A ring that is even slightly undersized for its fitting will not hold a seal no matter how carefully it is installed, so matching the exact diameter matters more with this part than with most small hardware on a backpack machine.
