1.0 out of 5 stars Quick Disconnect ... Always Disconnected, May 30, 2000

By A Customer

True adapter quickly connects to hose and is air tight, but ... disconnects (while in use) from tool (table saw, jointer, planer, etc.)

As another review stated, this item keeps disconnecting. It even does it while not attached to a DC hose!

I generously gave this 2 stars.

I bought 1 of these because quick disconnect is a great idea, especially with my little portable dust collector and I wanted to see if this could work.

I put it on my hose and tried to connect it to my Jet jointer and it just fell right off! I pushed and twisted and it slid off again and again. Tried it on my table saw which has the dust port upside down which will actually help something fall off given the weight of the hose and gravity and it did fall off.

I marched down to a local retailer that sells these and they all did the same thing on their equipment.

Where these did seem to work better was connecting them to blast gates where the seemed matched to each other. They would not reasonably connect to any jointer or tablesaw outlet. I tried a half dozen different combinations.

I wondered how a company can produce something that was a great idea but wouldn't connect to the equipment it was supposed to connect too. I thought I was using the wrong pieces or missing something. The sales people told me that some machines are different and sometimes things just work by trial and errror. That was hardly a reasonable explanation for me. I thought that all the parts from a given brand come from the same mold. I tried cross brands and they were all identical. 2 brands I worked with, Jet and Delta.

So I thought that maybe I should make a pig tail to lay on the ground to plug into. That way gravity won't work against me in either situation.

Before I wanted to waste money making pig-tail 4" hoses I tried one idea. DUCT TAPE.

I hate the idea of duct taping anything other than ducts but i didn't have anything too lose at this point.
Here goes... I wrapped one revolution of silver duct tape around the dust collection outlet of my jointer. This quick disconnect went on beautifully. I was shocked! I think it does 2 things, It obviously increases the friction area to help make a tighter fit and it also is a different material and texture that seems to provide a better grip.

2 hard. slippery plastic surfaces, the dust collector outlets from the machines are slick and tapered naturally making the attaching quick disconnect fitting want to slip slide away from each other. Seems that research and developement should have researched a bit better.

I duct taped the outlet of my tablesaw as well and the fit seems fine. I believe I can enjoy quick disconnect ability now.
