Non-standard Thread On Cube?

[plaidpaint]

I bought a fresh wort in a 15L cube from my LHBS, with the intention of reusing the cube as a mini-fermenter for experimental 10L brews. I've discovered, however, that the threads on the cube are different from any of the taps that I own. Is this a common problem, and does anyone know where I might be able to get differently-threaded taps?

I have a cube that has a non standard thread on it. I don't know whether its common but it does happen. Maybe go back to the lhbs and see if they have fittings for that type of cube?
