Shop Vac Hose Adapters, Flex Hose to Smooth Duct
Join your hose to your duct so the air keeps pulling dust away from the tool, not into the room. The barbed end grips corrugated hose. The smooth end slips into your duct. Same-size and cross-size adapters from 1-1/4 inch to 6 inch. Made in the USA.
What Is a Shop Vac Hose Adapter?
A shop vac hose adapter is a fitting that joins your hose to a duct of a different size or type. It grips the hose on one end and the duct on the other. That lets you connect a corrugated flex hose to a smooth pipe, or step a small hose up to a bigger duct, without a pile of mismatched parts.
The smooth path inside the adapter matters. Ridged hose traps dust and slows the air. The smooth bore cuts that drag, so the suction stays strong and more dust ends up in the bin. Stronger pull at the tool means cleaner air and less sweeping when the job is done.
Why a Hose Adapter Keeps Your Suction Strong
Corrugated to Smooth
Ridged flex hose traps dust and chokes airflow. Our adapter gives the air a smooth path from hose to duct, so you cut the turbulence and keep the pull strong at the tool.
Cross-Size Transitions
Need to connect a small shop vac hose to a bigger duct? One cross-size adapter handles the diameter change and the corrugated-to-smooth transition. So you skip the stack of fittings and the leaks they bring.

Shop Vac Hose Adapter FAQ
What is a shop vac hose adapter?+
A shop vac hose adapter is a fitting that joins your hose to a different size or type of duct. It grips the hose on one end and the duct on the other, so the two pieces connect and the air keeps pulling dust away from your tool. Add a wrap of tape at any joint that sees heavy use.
Why use a smooth adapter instead of corrugated hose?+
A smooth bore moves air with less drag than a ridged hose. Corrugated ridges trap dust and slow the air down. The smooth path inside our adapter cuts that turbulence, so your suction stays strong and more dust ends up in the bin.
What size shop vac hose adapter do I need?+
Every hose adapter lists both of its sizes: the hose end and the duct end. Pick the one that names your hose size and your duct size. If your hose is an odd size, the builder takes your measurement.
Do you have a Festool 27mm or Makita 36mm adapter?+
Not as a ready-made part on this page. Every adapter here is a standard hose and duct size. For a Festool or Makita style port, start in the builder.
Will the barbed end grip my hose without a clamp?+
In most setups, yes. The barbed end is shaped to bite into corrugated hose ridges and hold on its own. Add a clamp if your hose is worn or you want extra grip.
Can I connect a smaller hose to a bigger duct?+
Yes. Our cross-size hose adapters change the diameter and the hose type in one part. So you can run a smaller shop vac hose into a bigger smooth duct without stacking a pile of fittings.
