Sump fitting to small bore pipe

[Pocster]

No matter how many ‘water’ fittings I have - never the right one .

The sump connector output is barbed - way too big . My pipe ( on the left ) with a nice and easy tap connector on at the moment .

Cant seem to find a suitable connector which ever way I try it ..

What do I need here ??

The one on the right looks to be the connector that comes with a big submirsible pump.  the multi barbed fitting is for connecting to different sizes of delivery hose.

 

Where does the skinny pipe on the left fit into this?  explain what you want to connect to what?

The left hand tap connector looks as though it will fit on the small threaded part of the right hand connector, if the small barbed bit is cut off. Then what do you want?

Won’t fit if I cut the barb off - thought of that

So many things . But for now a generic connect any size pipe to any other size pipe magic thingy

That’s for a watering system - so has to be a skinny

So is the left hand connector a 3/4" BSP.

I think so . I only stuck that on to test with a threaded tap - so it’s not a requirement to have that .

3D print whatever you require.

Yeah but I’ve got to design a thread and correct size barb - success rate at that design is zero .

Stupid ugly quick option: Buy/find a short length of hose that fits the barb and a barb to male BSP adapter, ala: 

 

You could probably find a reducer that goes straight from barb to your tiny hose though if you look.

 

What are you actually trying to do? Going from such a big outlet to the piddly hose suggests maybe need to go back to the drawing board.

Can I enquire why you want such a tiny hose ultimately connected to such a big fitting.  It seems very unusual to say the least.

[Onoff]

Just find the two thread sizes and print a M/F adapter? Then do away with the barbed bit altogether.

If you can find a blank for that rather than a fitting (either male or female - assuming that right angle is the same diameter/thread at each end) you could always get one of these and tap the plastic (you'd need the tap too of course):

Still, the question keeps being asked, what are you doing? If you are just using a big tank as a water source to feed a pumped irrigation system then don't bother with any of this just get a submersible pump and put it in the tank with the little hose attached. Or, see if you can't find a different outlet/drillable boss on the tank to use rather than this huge fitting.
