This clamp ring screw (Part #H491B) is a replacement screw that holds the clamp ring in place on the Rainbow D4 and D4SE water basin vacuums. The clamp ring forms the watertight seal between the upper and lower housing, and this screw keeps it drawn tight.
If a screw loosens or falls out, the clamp ring cannot hold full pressure and the seal weakens, which risks water leaking during operation. Keeping spares on hand makes reassembly after deep cleaning quick and keeps the basin sealed the way it should be.
- Fits: Rainbow/Rexair D4, D4SE
- Function: Secures the clamp ring for the watertight seal
- Benefit: Maintains the seal and guards against leaks
- Tip: Keep spares for reassembly after each deep cleaning
The screw threads into place exactly as the original did. Verify your model before ordering so the clamp ring seals the basin tight.
