MIRKA Vacuum Block Disc - 125mm, 5 Pack

The Mirka Vacuum Block Disc 125mm is an essential accessory for wet sanding applications where the vacuum system cannot be switched off. Designed to protect your sander and dust extraction unit, this disc acts as a barrier—preventing moisture from entering the machine and causing damage to internal components.

Ideal for trades and professionals who rely on dust extraction for dry work but occasionally need to wet sand, this simple yet effective solution ensures your gear stays safe and functional. It fits any standard 125mm sander and is compatible with hook & loop systems for easy attachment and removal.

The Vacuum Block Disc doesn’t interfere with your sanding performance—it simply safeguards your equipment when working in wet conditions. Whether you’re doing automotive finishing, marine work, or surface prep, it’s a smart addition to your kit.

Mirka Vacuum Block Discs 125mm should be used if the vacuum dust extraction cannot be disconnected during wet sanding.

This product is also available in a 150mm diameter.
