Iam making a DIY cool tube. Iam gonna glue the rim of the glass tube, to the rim of a plastic increaser reducer.

I was planning on using a superglue that was meant to bind plastic and glass. I emailed the superglue company asking the temperature range of the superglue. They returned my email saying their clear glass adhesive has a maximum temperature range of 150F.

My cool tube will be air cooled via duct fans, but Iam concerned that the temperature inside the tube will get too hot. Although 150F is pretty hot, and if inside the cooltube is 150F outside of the cooltube will probally be like 120F, which will not be likely since Iam using an air cooled cooltube.

So do you guys think I can use clear glass superglue for my cooltube?

150F is nowhere near as hot as an HID gets (in the 1000s). I would guess that superglue may melt, you can use it, but if you plant on having your light on without constant exhausting than you may want to consider something else.

Oh I will definitely have constant exhaust on when my lights are on, Iam using outdoor air to cool my cool tube and not room temperature air. I might also have the lights on at night using outdoor air at night to cool my cool tube.

So do you guys think the clear glass superglue would work?

yeah I guess, I turn my fan off at night sometimes when I go to sleep, so I don't have to hear the tube sucking in air. Its kind of annoying I wish I could mmuffle it somehow.

Try wearing ear plugs while sleeping. You can get these soft foamy ear plugs, its used in really loud work conditions. It should help muffle sound.

my computer fan is pretty loud, but when I sit at my desk with those ear plugs on I cant hear the computer fan at all.

You should give it a shot. I would be just as worried about the plastic reducer melting. I think if you have a constant airflow like dbo24242 said you shouldn't have a problem.

Use the O clamps things. Dont use superglue.

sticky tape?

I'd say no to that as well. From my experience heat and tape don't work very well together.
