OVERVIEW

Technical Overview: Walter 48M404 Sealing Flange

The Walter 48M404 Sealing Flange is a critical component designed specifically for the Line-Mate III linear finishing system. This precision-engineered part serves a dual purpose: it acts as a mechanical mounting interface for abrasive accessories and, more importantly, provides the necessary airtight seal for Walter pneumatic drums (such as part number 07-F-037). In linear finishing applications, the pneumatic drum is inflated to provide a cushioned surface that conforms to the workpiece, allowing for uniform satin finishes and scratch removal without gouging the base metal. The integrity of this air cushion relies entirely on the sealing flange.

Manufactured from high-grade steel, the 48M404 is built to withstand the torque and rotational forces generated by the Line-Mate tool, which operates at variable speeds to suit different finishes. A compromised or worn flange can lead to air leaks, causing the drum to deflate during use, which results in uneven finishes, increased vibration, and potential safety hazards. By utilizing the genuine 48M404 flange, operators ensure that the pneumatic drum remains concentric and fully inflated, maintaining the optimal contact patch with the metal surface.

This component is essential for MRO (Maintenance, Repair, and Operations) environments where the Line-Mate system is heavily utilized for stainless steel fabrication, pharmaceutical tank finishing, and food processing equipment maintenance. The flange is designed for easy removal and installation, minimizing downtime during accessory changes. It is compatible with the standard 5/8"-11 spindle architecture found on the Line-Mate III, ensuring a perfect fit without the need for adapters or modifications.

FAQ

It is designed to secure the pneumatic drum to the Line-Mate tool and create an airtight seal to keep the drum inflated.

No, this flange is specifically designed for the Walter Line-Mate III linear finishing system and its specific spindle configuration.

It is often included with the tool kit or the drum assembly, but this SKU represents a replacement part sold individually.

It is made of durable machined steel to withstand industrial use and high rotational forces.

It is primarily for the pneumatic drum. Other wheels, like flap wheels, may use different mounting hardware or standard keyway systems.

If your pneumatic drum loses air pressure during use or if the flange threads/faces are visibly damaged, it should be replaced.

It is compatible with the Line-Mate III (30-A 268). Check your tool's manual for legacy compatibility.
