PVC to glass

[tydtran]

What would be the best material for gluing PVC pipe to glass?

How about acrylic to glass?

please elaborate ... what type of application is this?
If the PVC pipe is going through the glass, it is generally connected using a bulkhead.

Also what type of application is the acrylic to glass? Are you putting baffles in your sump?

The only time you can get away with gluing plastic of any sort to glass is if there is no pressure on the connection. Silicone works great if it isn't a critical thing, for example gluing acrylic baffles into a glass sump.

The silicone sticks really well to glass, but not at all to the acrylic. Baffles are fine because the silicone sticks to the glass and 'clamps' the acrylic in place, without properly adhering to the acrylic surface.

Sorry for not giving enough information.

I want to make an overflow out of PVC pipe. I plan on cutting the pipe in half lengthwise and gluing it to the wall and bottom of the aquarium. Pressure should be equal on both sides of the PVC so I don't think it has to be a strong join as long as the PVC just stays in place.

Oh I see.
I've heard Mr. Sticky's underwater epoxy works or Weld On #810. The pvc should be roughed up to stick better. Sounds like you're cutting it, so it should be rough enough.

A good quality silicone... as they use on the AGA overflows...

Thanks for the input.
