Eheim 1250 1/2" ??
Which adapter do I need for inlet of eheim 1250?
I'm trying to build 1/2" sys but only outlet seems to be 1/2" compatible...How did you guys solve this problem?

According to eheim's own specs;
Inlet (suction side) = 3/4"
Outlet (pressure) = 1/2"
Though I can tell you as an owner of one, that the outlet is smaller than 1/2" once you adda barb, and the inlet is just over 1/2". I use 3/8" silicon tubing and it fits very well on the outlet (perfectly infact, 1/2" my arse), and I've managed to stretch it over the inlet. It was a struggle, but doable with patience.
If you're gunna use 1/2" tubing, it'll fit nicely on the inlet, but will probably have to be hose clamped to the outlet.
*counter edit* I really don't care how angered you are, if you circumvent the swear filter again you will be banned.

Leggysoe, just boil some water and hold the ned of the hose you want to put on the inlet in the boiling/boiled water for a minute or two, that'll soften it up and you can easily stretch it over the inlet barb. The problem you'll probably have with wanting to go all 1/2" hose is the outlet, it will be a bit of a loose fit so you'll definitely need to put a clamp on it.Thank you Baby. I love you.

What he said about boiling and clamping... I just finished assembling home made sys with 1250 and 1/2 inch tubing. Just use the stock plastic barbs that come with the pump, avoid kinks and tight turns, and your flow will be just great. I was going to put new and bigger barbs on but testing the pump stock showed excellent flow, so I abandoned that bright idea for now. If you do put new ones on, be sure that the inside diameter of the inlet is at least 1/8 inch larger than the ID of the outlet.1:A7N8X-Del Gaming, game modding/Linux/server

IF you want just go to home depot and put up 1/2" by 1/2"NPT and 1/2" by 3/8"NPT plastic barbs and replace the stock ones.Media Server | Norco RPC-470 | GIGABYTE GA-890XA-UD3 | Phenom II X4 925 Deneb | 8gigs G.SKILL Ripjaws PC3 10666 | 64gig Crucial M4 | x2 2TB Samsung F3 | x2 1TB Samsung F1 | x1 2TB Samsung F4 | 500gigs Seagate 7200.10 | Sapphire HD4830 HDMI | Corsair 650hx
