Review on 💪 POWERTEC 70179 Y-Fitting, 2-1/2", Black - High-Performance and Durable Y-Fitting for Optimal Airflow by Allan Lambert

I ordered various Powertec couplers and a large dust cap to make a dust cap/collection system for my table saw. I deliberately ordered all products from the same brand to avoid problems with the choice. Unfortunately nothing fits my vacuum cleaner hose or inlet. Sometimes the specified joint diameter is the outside diameter, sometimes the inside diameter. Is it really that difficult to include both the inner and outer diameters in the product description? The elements work as designed if a proper connection is possible. Surprisingly, the product listing on the company's website doesn't include two-sided, preferably stepped, connectors that would allow a connection. I wrote to the company via their website over a week ago for advice on how to tie these things - no response. I'll try duct tape, or maybe a flexible rubber boot can be made to work. Insufficient product description without customer service.
