A reducer for actual woodworking dust-hose sizes
This hose-to-hose reducer connects a nominal 4 in hose to a true 2-1/2 in hose. The small end is built around a 63.50 mm bore—not the smaller 57.15 mm cuff often hidden behind a “2-1/2 in shop vacuum” label.
Nominal fit profile
- Large end: male plug, 101.10–102.10 mm OD taper.
- Small end: male plug, 63.00–64.00 mm OD taper.
- Approximately 40 mm engagement per side; 45 mm transition; 125 mm overall length.
- Material/quantity: black PETG; one reducer. Hose clamps are not included.
Submit both free hose IDs and identify whether each connection is flexible hose or a rigid port. If the small side is near 57 mm, choose a shop-vacuum-interface product instead.
Made to order: Production normally takes 10–14 business days after fit confirmation; shipping time is additional.
Compatibility: DustFitter products are independently designed replacement adapters. Brand and model names are used only to identify compatibility. DustFitter is not affiliated with, authorized by, or endorsed by the referenced equipment manufacturers. Trademarks belong to their respective owners.
Safety: For ordinary shop-vacuum and woodworking dust-collection use only. Not rated for combustible-metal dust, explosive atmospheres, hot ash, liquids, pressure service, or life-safety applications. Printed PETG is nonconductive and does not ground a dust system. Follow equipment instructions and replace any part that is cracked, loose, deformed, or worn.
