Product Description

The POWERTEC Dust Control Flex Cuff with Hose Clamps, 4-Inch, delivers an airtight connection from one dust-collection fitting to another of comparable size, while eliminating the need for flimsy duct tape connections or other permanent fasteners. Firm yet pliable rubber construction allows enough flexibility to bridge slight diameter differences in hose or tubing. Pre-molded indents on the cuff allows for easy, airtight clamp installation. Handy set includes one rubber cuff and two steel hose clamps.

Customers like the fit of the hose pipe fitting. They say it fits fine, has the perfect diameter, and won't pull apart after this. The rubber seals accommodate slight differences in size, making it handy if you have to incorporate slight differences into your design.

The diameter is 3-7/8", which perfectly fits all those plastic adapters out there that won' t fit on the original.

Works perfectly!
5 Stars
Works perfectly!
I used this to connect the 4" output from my cheap Harbor Freight dust collector to a 4" to 6" adapter (which in turn went to a 5-micron Rockler dust bag). The two included hose clamps hold it tightly in place. A bit Rube Goldberg-ish but it works. This clamp is thick enough that I expect it to last many years.
