Hi, so my old 60w co2 laser tube died on me after a lonnnnng time of use so purchased a new one, on receiving it from the courrier it was damaged in transit one of the water inlet pipes had broke at the bend (see photos) the company had shipped me a new one but told me i can keep the broken one.
The question i have is can it be fixed? I was thinking of extending the silicon water pipe and using some silicon seal to seal it all or even some epoxy? What are your thoughts?

      Instead of trying to put epoxy around the silicone tube and glass I’d suggest trying to build-out the broken portion of the glass, allowing you to attach the silicone tube in a normal way.

1. thoroughly clean the glass
2. carefully file down any hard edges that might act as a stress point. There may be some benefit to lightly abrading the glass where the epoxy will be applied
3. insert a well fitting cylindrical object down the middle of the glass opening to serve as a form. Apply some sort of mold release or release agent to it as you’ll be applying epoxy against this piece.
4. carefully form the epoxy over the form ensuring good bonding with the existing glass substrate. Do your best to conform to the existing shape. Be generous with the epoxy.
5. allow the epoxy to partially cure, then carefully remove cylindrical form.
6. allow epoxy to fully cure
7. pressure test
8. profit
