When you’re building a dust collection system and you’re connecting a hose to the cabinet saw, you probably don’t need to remove the hose very often, so a regular hose clamp will do the job fine. But for a mobile tool, you might want a clamp that you can easily remove and replace without trying to find a nut driver (or wrestling with a slotted screwdriver).
EZ Release hose clamps from Peachtree Woodworking Supply are designed to be removed and replaced quickly and without tools by simply by squeezing the ears. These clamps fit over the hose when you squeeze the ears and constrict around the hose to keep it in place when you let go.

When I was at the Woodworking Show, on a lark I picked up a 2-1/2″ EZ release hose clamp. I found it really useful for my CNC where I need to periodically remove the hose from the dust boot.
Left Threaded vs Right Threaded Hose
One thing I discovered when I was using this clamp was that due to the direction the ends of the clamp overlapped, it fit better over left threaded hose than right threaded hose.
When it’s over the left threaded hose, you can see it follows the wire in the hose and sits in the gaps between the coils. The clamp will put pressure directly on the dust port, making a snug connection.

When it is over the right threaded hose, no matter how much you maneuver the clamp it will always go over one of the wire coils. While it still makes an okay connection, it is not nearly as snug as with the left handed hose.
You can purchase the EZ Release hose clamp in either 2-1/2″ or 4″ sizes. On the Peachtree website you can find the 2-1/2″ clamp for $1.80 and the 4″ clamp for $2.50. Shipping there is $6 for orders under $15.

Does anyone happen to know where I could find something like these “Constant-Tension Spring Clamps” but inside out? In other words, I could put them inside a ~4″ hose and have it expand on the inside of the hose.
Also it needs to probably be made from 302 stainless steel.

Benjamin,
Nice. I could use a couple of those.
I wonder if you can open the clamp far enough to swap the clamp end for better fit on right threaded hoses? I suppose there is always risk of deforming, but should be able to restore the correct clamping range.

Good suggestion, I had thought about that, but didn’t think it would work because the ears would interfere with each other.
I just tried it now. It was a little difficult getting the ears to go past each other, but after some grunting, I got the clamp switched to right threaded.
It definitely took some spring out of the clamp. Even when I try to bend it back it doesn’t seem to be as “springy”. It still works though.
After switching it back to left handed thread it definitely has lost some of its spring. Again it still works, because it has enough to spare, but I wouldn’t switch these from one “threaded” to the other very often.

Won’t it work on right-handed if you flip it upside-down?
Benjamen
No, can you thread a left handed nut on a right handed bolt after you flip it upside down?
But see the previous comment and reply, you can change the “threadedness” by opening up the clamp far enough so that you can pass the ears by each other, but it stresses the clamp.
Benjamen
Oh, and I did actually try flipping it upside down, turning it around, and using the other end of the hose, before I slapped my head with my palm and thought “of course that won’t work”

Nice and simple.
I have a mix of round duct and hose sizes in my dust collection system. It starts out as 6 inch diameter – then some 4 inch and then some 2-1/2 inch – and some metric sizes for my Bosch miter saw and some portable tools. I have a different style quick release band clamps that were all metric sized and use a lever to tighten-latch them in place – and a worm screw adjuster to snug them up before latching. I don’t recall where I got them – but I think they are the Protex brand

I have had some of these. Found that they were not very tight at all.
Ended up going with gear clamps meant for these hoses and had a nice thumbscrew.
Got them from Peachtree as well.

I just took a look at the current pricing for the Protex Clamps in the 70-115 mm size – which would handle 4 inch. I think that I have about 6 to 8 of this size – and do not recall having paid anything like current prices – but here’s the link:

Crap, why did it not occur to me that there are right hand and left hand “threaded” hoses? Here I was thinking a moron designed the DustRight hose clamps I have. Turns out they’re for right-handed hoses, and I’ve got a left-handed HF hose.
