Eheim 1250 Fitting Size ?

What is the thread size/diameter for the hole in the outlet side of the pump. It looks like 3/8 npt, but I wanted to make sure it wasn't metric before I bought some fittings for a project.

Thanks,
Chris

i have a eheim 1250 i can't find a fitting for, and yes i think it is 3/8 npt but metric so it requires some telfon tape. If you do find fittings for it please post info on it i would like to have it ready as a backup return pump. The 1250 was my original choice but ended up ordering an OC 2500.

If a 3/8" mpt thread will work, Spears makes an adapter to 1/2". http://www.spearsmfg.com/

D&T pet supplies carries them. If you just need the orriginal fitting for connecting to flexible tubing, you could find that at Eheimparts.com. Actually, I just looked there and it shows the threads as 3/8, so that answers that question :)
