How do you make these air-tight?

I've seen various versions of these around. With these two particular types, I wonder how you connect the hoses such that they remain air tight. The holes don't seem to have shoulders, just a hole through the thin plastic. I don't know how you'd keep them air-tight.

Anyone have one of these?

Thanks,
Phil

Most often the hose ends are slightly tapered. The suction in the system will pull the hoses in and keep 'em tight.

I had one a while back and the lid was tight, and the hoses fit as tight as if they were pushed into the shop vac hole. They didn't leak. Maybe I got lucky.

I have both sizes of the LV units.
Loring is right about the hose ends being tapered, but what I did on my 4" unit hooked to my DC is turned the hose directly into the lid.
Either way, even with the smaller unit and shop-vac, there is never an issue about airtight.
My shop-vac actually sucks the garbage can in when it's turned on.

I was pondering the same thing. I bought a lid from Rocklers a few weeks ago and have been looking at it thinking their has to be a good way to hold the hose in the top. I was thinking of using silicone to seal/glue the hoses in there.

And what about the top to the can? I was thinking I would get some foam weather seal.

Not really necessary for the small units on a shop-vac.
Believe me when I tell you that you won't need to seal it when the shop-vac is on. On the 4" for DC, not a bad idea as the suction isn't as great.

BTW, I've looked at the Rockler one (ShopFox and Busy Bee have same unit) and personally think the LV is better quality.
