Festool Hose Connector Came Off

[Eurotex]

The rotating hose connector for my CT-22 dust collector came off the end of the hose.  This is the connector at the working end, not the end that connects to the machine.  Even though it is internally coarsely threaded, I cannot get it to thread onto the end of the hose.  Has anybody else ever faced and solved this problem?

Piece of cake!!!  Look carefully at the sides of the connector itself.  There are two diametrically opposed recesses just below the end closest to the hose.  Take a small screwdriver and carefully insert it into each in turn to release the end ring of the connector.  Slide that ring by itself onto the hose a foot or so.  Then screw the remainder of the connector counter-clockwise (or left-handedly) onto the hose.  Then slip the ring down to the connector and snap it back into place with the tabs aligning with the recesses.  Pat yourself on the back for a job well done.

Welcome to the forum!

Here's a link that shows how it is done: Fixing a separated dust hose connector

The tool-end and vac-end fittings all work the same way.   [big grin]

Thanks, Sparktrician.  It was quite easy, but I didn't know the technique.  My weekend looks better now.

Unfortunately, millions of times. Known problem.

That's how it's done. I myself did it many times this way. Until I realised it was the stupid way.

Next time, just slip your finger down the hole of the nozzle. You'll feel you can touch the inner ring. Just hold it down with your finger so it won't turn and keeping it like that you can screw the nozzle back on the hose. No need to disect it.

Btw, this won't solve the problem forever. Once the nozzle comes off the first time, it will keep on coming off more and more. Not what you'd expect of a $100+ hose.

If the hose connector comes off on a regular basis, you should check the ring Matthew is holding in the "step 3" pictures. In my case there were scratches on this ring, after I sanded the scratches away and sprayed some dry silicone lubricant on it, the connector hasn't come loose since. This was almost a year ago, the scratches were probably caused by grinding dust, I used the CT with a wall-chaser before getting a dedicated vac with electromagnetic filtercleaning for this purpose.

(BTW, even if there aren't any scratches, I think lubricating the thing would help)

Alex, the post I quoted was almost 5 years ago, and the hose end only came off once more since (and I'm not even sure it was the same hose (I have several 27mm hoses)

Happens all the time with me, multiple times per day. I've had three 27 mm hoses by now and it happened with all of them.

The way you move probably has something to do with it. I'm always turning and twisting and holding the sander in different positions and directions when I'm working on a house. The plug it cords always end up wrapped around the hose. Same when I'm cleaning. So that puts a lot of strain on the nozzle, a lot more then when you only connect it to a saw for instance.

Mind you, this NEVER happened to me when I used vacuums of another brand. And I've used plenty.

In the end the connection of the inner nozzle ring to the hose is only a friction fit, and as it is, the soft rubber of the nozzle puts a lot more friction on the inner ring than the hose that is made of a harder and smoother plastic. The nozzle is specifically made to have a lot of friction so it would fit well over the 27mm port of some tools as well as inside the 36mm ports of other tools.  

I think it would have been a better design were the inner ring locked in place by some sort of positive stop (like a C-ring) or glued in instead of relying on friction only.
