Genuine Makita 421815-6 — Dust Seal (8 mm)
Keep your Makita jigsaw running clean: this original Makita dust seal (part no. 421815-6) is a small 8 mm seal designed to block dust and chips from entering the gear/shaft area of the tool, helping protect internal guides and bearings and extend service life.
The seal is made to the same specifications used in Makita parts diagrams and fits into the jigsaw’s gearbox/guide housing for a simple replacement during routine repair — durable, fitted construction for a snug installation.
Example models (for reference) include several Makita jigsaws and related reciprocating models that list this part in their parts diagrams, for example DJV182, BJV140, BJV180, SMA400.
