Introducing the 4-Inch Dust Control Flex Cuff with Key Hose Clamps by POWERTEC.
This coupler is designed to provide you with an airtight connection between a pair of 4" dust collection fittings or hoses. And it comes equipped with standard hose clamps so that you won’t need unattractive duct tape or a messy assortment of screws. It's a highly useful (and reusable) dust collection system accessory, as it allows you to interchange fittings and connect adapters to keep all of your dust collection tools connected.
Compatibility
These Flex Cuffs work exclusively with nominal 4" OD ports, hoses and fittings.
Construction
It's made with high quality rubber to ensure long-term durability and possesses a flexible profile capable of conforming to the narrow range of sized ports.

This was needed to connect my CNC to my wen dust extractor, had a 2 inch hose up to a 4 inch opening which has to connect to another 4 inch inlet on dust collector, both have 4†OD, and as you can see from pic, it worked perfectly.The thumb screws are a bonus, makes installing it a breeze.So if you’re looking for something to connect 2-4†hoses together, this is what you need .Arrived exactly when it said.Power tech is actually a decent company. Haven’t had to work with their customer service, so I cannot speak to that but their products are decent.

Used these in a not so typical manner to connect my dryer duct to a booster fan under the house. The couplings make it (relatively) easy to disconnect the fan and remove for cleaning, then reconnect when finished. Even though it’s had to maneuver under the house between joists, these make it much easier.

Used this along with a POWERTEC 70181 to extend the dust port on my Dewalt DWE7480 out beyond the stand in order to use a POWERTEC 70354 on it!

So many shop-vac style hoses and fittings almost fit-this allows them to work together. Nicely made and easy to use clamps.
