Eheim 1250 fittings

[NewBlackDak]

Anybody know what size the threads are on the 1250? I got a little carried away when tightening the clamp, and mine are warped now.
They sort of go back to round when you put the hose, and clamp back on, but I don't want them to crack or cause a flow problem. I'd like to replace them with brass or chrome parts.

Thanks for your help

you can use 1/2 barbs ,but i prefer using 3/4 inlet, less restriction, cavitation and high head.
