3M 7100007820 Dust Free Hose Extension Kit

Product Description

The 3M 7100007820 is a whip hose extension kit designed for use with dust free sanding blocks. It extends the vacuum hose connection between a dust free sanding block and a portable vacuum or dust extraction unit, helping keep the work area cleaner during dry sanding operations. The kit weighs 1.12 pounds and is sold as a complete kit. It is typically installed by body shop technicians, finish carpenters, painters, and surface prep professionals who rely on dust-free sanding systems to meet air quality and cleanliness standards on the job.

This hose extension kit is suited for automotive body repair, woodworking, and general surface preparation environments where dust free sanding blocks are already in use. It provides additional hose reach in situations where the standard hose length is insufficient for the work area or equipment layout. The kit is intended as an accessory component within a larger dust extraction sanding setup rather than a standalone product.

Key Features

• Extends hose reach for dust free sanding block systems
• Compatible with 3M dust free sanding block configurations
• Sold as a complete kit with all necessary extension components
• Lightweight construction at 1.12 pounds for easy handling

Compatibility

Designed for use with 3M dust free sanding blocks that accept a whip hose vacuum connection. Refer to your dust free block model documentation to confirm hose fitting compatibility before installation.

Installation Notes

Installation is typically performed by the end user or shop technician without specialty tools. Ensure the vacuum or dust extraction unit is powered off before connecting or disconnecting hose extensions. Verify all fittings are fully seated and airtight to maintain proper suction and dust capture efficiency. Follow the equipment manufacturer guidelines for maximum hose run length to avoid loss of extraction performance.
