Description
Overview:
This Genuine Makita Line Filter (part no. 688172-7) is a sealed inline suppression module used to stabilise electrical performance in selected Makita power tools.

Intended for use in hammer drills and other Makita machines, it is a direct-fit replacement in models such as the DHR164 rotary hammer and BBO180 sander. Built to Makita's specification for durability and vibration resistance, it restores the tool's original noise-suppression capability and helps protect sensitive components over time. Ideal for routine servicing or when replacing a damaged or failed filter during a wiring or switch repair.
