I'm drilling a clear plastic shoebox to turn it into a flow-through fry incubator that will sit on a glass shelf just above the tank.

The fittings leak a little, which is not a big deal, but I suppose I should seal them up.

Can anyone recommend a non-toxic, water proof plastic sealant that will bind plastic and pvc?

The only thing I know is Silicone...... I have used a bit of the cpvc cement before to glue rigid tubing to a piece of pvc for those little elbow filters (see notes on Dave Snells filters) but, I am not absolutely certain whether or not it is toxic.... I imagine once its dry, and not a lot used, it should be ok... afterall.... I havent had any problems doing that....

Thanks. I thought silicone only sealed glass, not plastic, but I'll give it a try.

If the holes are drilled very tight you can use clear PVC Cement it will out-gas in 24hrs. If not you can use threaded fitting (nipple) and place a small rubber washer and plastic nut on both sides. HomeDepo or Lowes carries a variety of things you can adapt to your needs. Niko

Yeah: Nicks idea would work best, but I know even though silicone doesn't "stick" to plastic like it does glass, it still would create a seal similar to a washer when dry.
