6 inch ABS sewer pipe will fit over it. There are many other sizes that will also fit. :D <ducks>

More important how tight of a fit do you need? 3/4 inch copper will fit over 1/2 inch copper. For a thicker wall, 3/4 inch iron pipe should fit.

Darn... I was just about to link to Bush getting shoes thrown at him...


Anyway, the easiest thing to do would be to go on McMaster and order structural or single-line tubing with the correct OD for a very tight fit. You could also just buy thicker wall tubing from them...

If you only need a very short sleeve, you could file the bump out of a copper solder coupling.

They sell copper couplings without the ridge for as much or less than the ridged ones.

They do? And they slide back and forth really easily?
Im going to sand on down and see what happens and i could put many on to cover a hole for battery or darts and just tape them together

Not if you 'tin' the ends then do half the joint at a time. It's all about heat control.
