Product Overview

The RUPES 6" (150mm) x 0.47" (12mm) Solid Foam Interface Pad, 2-Pack (981.324) 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 solid, no-hole design is suited to sanding applications where dust-extraction holes through the interface are not required. This makes the 981.324 a useful option when working with compatible solid sanding discs, non-vacuum sanding systems, or applications where increased abrasive conformity is the primary objective.

The 981.324 is sized for compatible 6" (150mm) grip / hook-and-loop sanding systems, including compatible RUPES professional sanders as well as other-brand 150mm sanding tools using a suitable 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.

Solid / No-Hole Interface Design

The RUPES 981.324 features a solid foam construction without vacuum holes. This configuration is intended for sanding applications where through-pad dust extraction is not required.

The solid interface provides continuous foam support between the backing pad and abrasive while retaining the added flexibility and conformity of the 12mm foam layer.

For applications requiring through-pad vacuum dust extraction, consider a compatible multi-hole RUPES foam interface pad instead.

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 solid 981.324 is best suited to applications where through-pad vacuum extraction is not required.
If maintaining through-pad dust extraction is important, the RUPES 981.323 12mm multi-hole interface is the more appropriate configuration.
The universal 6" (150mm) format allows the interface to be considered for compatible RUPES and other-brand professional sanding systems when the diameter and attachment system match.
For flatter surfaces where less conformity is required, a thinner interface or direct abrasive-to-backing-pad setup may provide a firmer sanding feel.

Frequently Asked Questions (FAQ)

What does the RUPES 981.324 foam interface pad do?

The 981.324 adds a soft foam layer between the sander backing pad and abrasive disc, allowing the abrasive to better conform to curved, contoured, and irregular surfaces.

What size is the RUPES 981.324?

The interface pad measures 6" (150mm) in diameter and 12mm (approximately 0.47") thick.

Does the RUPES 981.324 have vacuum holes?

No. The 981.324 features a solid / no-hole configuration.

What is the difference between RUPES 981.324 and 981.323?

Both are 6" (150mm) x 12mm soft foam interface pads. The 981.324 is solid with no holes, while the 981.323 features a multi-hole configuration for compatible vacuum sanding systems.

Where does the foam interface pad go?

The interface pad installs between the sander's backing pad and the grip / hook-and-loop abrasive disc.

Can this interface pad be used with other brands of sanders?

It may be used with other professional 6" (150mm) sanding systems when the backing pad diameter and grip / hook-and-loop attachment are compatible.

How many interface pads are included?
