Specifically
designed for endoscope water-air ducts—effectively removes stubborn residues, mineral deposits, and organic
soils.

in multiple standard sizes (compatible with most endoscope brands/models) and
supports custom dimensions. The brush diameter and length are calibrated to
match the exact inner diameter of water-air ducts (typically 1–3mm), ensuring no dead
