Rainbow D4 Flange Plate Scr...

Product details
These plastic-type flange plate screws (Part #H542B) secure the flange plate on your Rainbow D4 water basin vacuum and fit the Rainbow/Rexair D4 and D4SE. Each screw threads into the plastic housing to hold the flange plate flat against its sealing surface.
When a screw strips or cracks, the flange plate loosens and no longer seats evenly. That gap lets air leak into the basin, which reduces the suction the machine pulls through its water bath. Fitting fresh screws pulls the plate back down tight and closes the leak path.
- Fits: Rainbow/Rexair D4 and D4SE
- Function: plastic-type screws that fasten the flange plate
- Benefit: a tight, even seal that protects suction
- Tip: replace the full set together so clamping pressure stays uniform
These install with a standard screwdriver as a direct-fit replacement. Confirm your model on the Rainbow data plate before ordering, and keep a spare set for maintenance day.
