Marine-Grade Rubber Backing Pads for Pneumatic Grinders

These rubber backing pads are engineered for pneumatic grinders used in demanding marine environments. Designed to provide a stable, cushioned base for sanding discs and abrasive wheels, they deliver consistent pressure and excellent surface contact for efficient material removal and finishing. Whether you are smoothing hulls, prepping decks, or polishing metal fittings, these pads offer reliable performance and extended service life.

Constructed from high-quality, oil-resistant rubber with a reinforced center hub, these pads withstand the vibration, heat, and moisture commonly encountered on board vessels. The precision-machined thread (5/8"-11 UNC) ensures a secure fit to standard pneumatic angle grinders. Available in multiple diameters, they are an essential consumable for ship maintenance and repair tasks.
