Festool Multi Jetstream2 Interface Pad, 6-in., 1-Pack (203351)

Festool 203351 Multi Jetstream2 Interface Pad is a soft foam interface pad for 6" (150 mm), 6 inch sanding setups. This is an interface sander backing pad designed for contour sanding, edge sanding, and other finish work where a standard hard pad can be too aggressive. Model Number: 203351. If you work on curved parts, molded profiles, beading, or body panels, this pad gives the abrasive a little cushion so it follows the surface more evenly.

The main reason to use an interface pad is simple: it helps reduce the risk of sanding through at edges. On flat stock, a standard setup is usually fine. On curves and transitions, though, it is easy to lean a little too hard and cut through a coating or round over a detail you wanted to keep. The extremely soft foam construction lets the sanding disc float more, which makes the cut more forgiving without changing the sander you already own.

Festool builds this pad as a damping element between the sanding disc and the sanding pad. In practical terms, that means less harsh contact on delicate surfaces and better control when the workpiece is not perfectly flat. The 9/16" (15 mm) thickness is what gives it that extra compliance, and that thickness is especially useful on shaped components where you need the abrasive to stay in contact without creating pressure points.

This pad also uses Festool's MULTI-JETSTREAM 2 design, so it is not just a piece of foam cut to size. The hole pattern is made to support dust extraction, which helps keep abrasive discs from loading up as fast. Clean abrasives cut more consistently, run cooler, and usually last longer. If you are already using Festool sanding discs and dust extraction, this accessory fits right into that system and keeps the whole setup working the way it should.

The hook and loop attachment keeps disc changes quick, which matters when you switch grits during finish prep. Material choice matters here too. Foam is the whole point of this accessory because it adds the cushion needed for fine finishing on contours. Instead of fighting the shape of the part, the abrasive can ride it with less risk of leaving uneven pressure marks.

Compatibility is straightforward. The Festool 203351 Multi Jetstream2 Interface Pad is sized for 6" (150 mm), 6 inch random orbital sanders and is specifically noted for use with Festool RO 150 and ETS 150 6 inch sanders. That makes it a smart add-on for painters, automotive refinish users, woodworkers, and finish carpenters who already run those machines and want better control on profiles and shaped parts.

Who should buy it? Anyone doing finish-sensitive sanding on edges, curves, or molded parts. If most of your work is dead-flat panel sanding, you may not need it every day. But if you touch cabinet parts, trim details, bodywork, or rounded components, this is one of those small accessories that can save a surface and save you from rework.
