SKU: 490253 | Brand: BIEN AIR
Replacement water-adjustment plastic knob for the FMS-2530 magnetostrictive scaler. The cosmetic outer knob that the operator turns to adjust water flow during scaling — purely a wear/cosmetic part that does not affect the underlying valve function.
Replace when the existing knob has cracked, the printing has worn off, or the friction fit no longer holds. Slides on/off the underlying valve stem with no tools required.
