Makita CUSHION 'P' DBN500 - 421551-4
Original Makita 421551-4 — Cushion "P": a genuine Makita rubber shock cushion that sits behind the piston to absorb impact and reduce wear on the main cylinder assembly. It restores smooth firing and helps prevent metal-on-metal contact in the nailer’s driving assembly.
Fits Makita finish nailers such as the DBN600 (64 mm cordless finish nailer) and is also shown as compatible with DBN500/DBN500ZJ and DBN600ZJ in Makita parts listings. This is the direct replacement cushion P (part no. 421551-4) designed to match the original shape and mounting points for a straightforward swap.
Note: this listing refers to the original Makita part so you’ll get the same fit and function as the factory installation.
