Customer Reviews:

It is a Quick Disconnect [Posted on 2001-11-06]
I don't know why I bought this, even after reading the other reviews. The logic of the quick disconnect to move from machine to machine seemed cost justified. However, the product will disconnect while in use, and even disconnect if not perfectly flat.

Rather than use this product, avoid, avoid, avoid. Set your dust collection system up with "Y" or "T" fittings to each machine with blast gates to control the air flow. This hard wired system, even though it cost more, will be much better system to operate and use without hassles.

No problems... [Posted on 2001-11-12]
I have experienced none of this disconnect problems of other reviewers. It stays attached to my Unisaw, jointer, portable planer and wide belt sander, all without difficulty. I do use a slight twist when ataching it to ensure a solid fit.

Works fine for me [Posted on 2003-08-18]
I was a little hesitant in ordering this after reading the initial user reviews here, but went ahead and bought a couple anyway. After attaching the two quick disconnects to a 10' flexible clear hose (made by Jet), I have been using it on various woodworking machines and my dust collector. So far, I have not experienced any of the disconnect problems expressed earlier. Perhaps the problem would occur if a shorter and less flexible hose is used. But these quick disconnects are a godsend for my small garage shop with most of my woodworking machines on mobile bases.

Disconnect too easily [Posted on 2003-11-18]
These don't work properly for me. After much frustration, I bought a system that has a positive locking mechanism ("FazLok" quick disconnect fittings available from Wordworker's Supply). The FazLock connectors work just fine with the PSI 4" hose.

I found a work-around [Posted on 2004-07-10]
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.
