Makita 423142-7 Sponge Rubber Tool Replacement Part for Sander Tools BO4550 and BO4552

The Makita 423142-7 sponge rubber is a replacement cushioning pad designed to restore proper sanding performance in compatible finishing sanders. This component sits between the sander base and sanding sheet, helping distribute sanding pressure evenly while improving surface contact during operation. Made from durable rubber sponge material, the pad provides the flexibility and cushioning needed to maintain smooth sanding results and reduce vibration during use. Over time the original sponge pad may wear down or lose its elasticity, which can lead to uneven sanding performance and reduced efficiency. Replacing the worn sponge rubber with this part helps restore the sanding surface support and improve overall tool operation. This replacement component is designed for compatibility with Makita BO4550 and BO4552 finishing sanders, helping maintain proper fit and sanding performance. Installation is straightforward and users should reference the tool diagram to confirm proper placement before installation.
