RUPES 3" Backing Plate

LHR75 Backing Plate for RUPES Mini Polishers

The RUPES LHR75 backing plate (part 990.007) is the 75 mm (3 inch) hook-and-loop plate for RUPES's 12 mm orbit mini polishers: the corded RUPES LHR75E, the air-powered LHR75 pneumatic polisher, and the battery HLR75 iBrid Mini. It mounts with one M6 socket cap screw (RUPES 9.820) through the center, using the hex key RUPES packs with the tool. Six holes around the hub vent the pad, and the hook face takes the 3-inch pads these machines run on bumpers, pillars, mirror caps, and spot repairs.

RUPES allows only 80 to 100 mm foam pads on this 75 mm plate, so stay in that range when you buy pads. To change the plate, remove the center screw, set the new plate in the center and turn it slightly until it drops into place on the spindle, then tighten the screw. Replace it once pads start creeping off center or the hooks stop gripping.

What Makes it Great:

🔁 Three Machines, One Plate: The same 990.007 fits the corded LHR75E, the pneumatic LHR75, and the cordless HLR75, so a shop with a mix of minis stocks one part.

🌀 Built for the 12 mm Mini Orbit: A 75 mm plate on a 12 mm throw keeps the pad turning on curved panels where a 5 or 6 inch pad would lift off.

🌬️ Vented Face: Six holes around the hub let air through to the back of the pad instead of trapping it behind a solid plate.

🔩 Single-Screw Mount: One M6 screw clamps the plate at the center, so a swap takes the supplied hex key and a minute of work.

Frequently Asked Questions

What size pads fit the RUPES 3 inch backing plate?

RUPES specifies 80 to 100 mm foam pads for the 75 mm plate on the HLR75 and LHR75E. A pad in that range overhangs the plate enough to protect the paint without flapping at the edge.

Will a 3 inch rotary or PXE80 backing plate fit the LHR75E?

No. The LHR75E, LHR75, and HLR75 take RUPES's screw-mounted 990.007. Threaded 5/8"-11 rotary plates and FLEX's quick-change PXE80 plates use different mounts and will not attach.

What screw holds the backing plate on a RUPES LHR75E?

A single M6 socket cap screw with washer, RUPES part 9.820, threaded through the center of the plate. Keep it when you swap plates, and replace it if the hex socket rounds out.
