Mosmatic Distributor Arm Assembly for 12" TYR Adjustable Duct Cleaner - 900.573

The Mosmatic 900.573 Distributor Arm Assembly is a replacement rotor arm for the 12" TYR Adjustable Duct Cleaner. It helps restore proper spray action when the original arm is worn, bent, or damaged.

This replacement part is built for Mosmatic duct cleaning heads used in pipes, vents, shafts, drains, and similar wash areas. The distributor arm supports rotating water spray inside the duct cleaner head. That spray action helps remove buildup from hard-to-reach interior surfaces.

Use this part to service a compatible 12" TYR Adjustable Duct Cleaner. Always confirm fit with your model before ordering. Replace damaged rotor arms before use to help protect the swivel and maintain safe operation.
