Product Overview

The RUPES 6" (150mm) x 0.47" (12mm) Multi-Hole Foam Interface Pad, 2-Pack (981.323) is a soft sanding interface designed to improve abrasive conformity when sanding curved, contoured, and irregular surfaces.

Installed between the sander backing pad and abrasive disc, the 12mm (approximately 0.47") thick foam interface adds flexibility to the sanding system, allowing the abrasive to better adapt to different panel shapes and helping produce a smoother, more consistent finish.

The multi-hole vacuum pattern allows the interface pad to be incorporated into compatible 6" (150mm) dust-extraction sanding systems while maintaining the flexibility needed for contour sanding and surface refinement.

The 981.323 is sized for compatible 6" (150mm) grip / hook-and-loop sanding systems, including RUPES professional sanders such as compatible SKORPIO models, as well as other professional 150mm sanding tools using a compatible backing pad and attachment system.

Sold 2 interface pads per package.

Why Use a Foam Interface Pad?

A foam interface pad is installed between the sander backing pad and the abrasive disc to add flexibility to the sanding system.

The additional 12mm foam layer allows the abrasive to follow panel contours and surface variations more easily than when the abrasive is mounted directly to a firmer backing pad. This can be especially useful when sanding curved panels, contours, transitions, and other areas where increased conformity is desirable.

The added flexibility helps distribute sanding contact more uniformly across the work surface, supporting a smoother and more consistent finish.

Multi-Hole Dust Extraction

The RUPES 981.323 features a multi-hole configuration designed for use with compatible vacuum sanding systems.

When paired with a compatible multi-hole backing pad and vacuum abrasive disc, the interface allows the sanding system to retain dust-extraction capability while adding a soft, conformable foam layer between the abrasive and backing pad.

Compatibility Note: Always verify backing pad diameter, grip attachment, and vacuum-hole compatibility when using this interface with RUPES or other-brand sanding tools.

SMSDistributors Expert Notes

The 12mm interface is a good choice when additional sanding-pad flexibility and conformity are desired on curved or contoured surfaces.
The interface installs between the backing pad and abrasive, allowing the sanding disc to follow surface shapes more easily than when mounted directly to a firmer backing pad.
The multi-hole configuration makes the 981.323 particularly useful in professional vacuum sanding systems where dust extraction needs to be maintained.
The universal 6" (150mm) format allows the interface to be considered for compatible RUPES and other-brand professional sanding systems, provided the attachment and hole configuration are suitable.
For flatter surfaces where less conformity is required, a thinner interface or direct abrasive-to-backing-pad setup may provide a firmer sanding feel.
