Crush-Resistant Spiral Duct and Fittings
A spiral seam makes this duct strong and rigid. Fittings have male ends with a slightly smaller diameter to press-fit into duct.
PVC-coated steel combines the strength of steel with the corrosion resistance of plastic.

Chemical-Resistant Duct and Fittings
Made of PVC plastic to withstand acids, alkalies, salts, and other corrosive vapors and fumes. Use PVC pipe cement (not included) to secure components. Fittings have female ends with a slightly larger diameter to press-fit over duct.

Design-Your-Own Dust Collector Duct System
Use these components (sold separately) to put together a duct system to collect sawdust, chips, shavings, and granular material from woodworking operations. Hose clamps are available.
For maximum safety and to avoid a dangerous buildup of static electricity, you must use the grounding kit (sold separately).
If you need more information on designing and installing a dust collection system, order our book "Dust Collection Basics."
Style G is a universal duct reducer and has seven outside dia. step sizes. Cut away unneeded steps with a hacksaw.
Style J is angled upward for easy connection between the machine and a shop vacuum.
