Ok help me here...how to get 5/8" tubing connected to 1" barb??

Ok, so I need your help here guys.
I have a mag canister filter I want to hook up in-line with a UV sterilizer. The mag canister uses 5/8" tubing which is a sort of weird size.
The input of the UV sterilizer has a 1" OD Barb, as well as a 1 1/4" male threads just above the barbs, so it could be hooked up either way.

So I need to find fitting(s) to get a 5/8" tube to hook to a 1" barb, or 5/8" tube to hook to a 1 1/4" male threads.

I have no idea where to find any 5/8 barbed fittings. This is very frustrating!
Anyone have ideas???

I believe you can get a 5/8 female (to receive the 5/8 tube) to 1/2 male thread adapter in the R/O dept of HD or Lowes. Then pick up adapter(s) in the PVC dept to go from 1/2 to 1 1/4 and your in business.

on second thought, it may have been 3/8 to 1/2 I recently saw there, I'd still take everything with you and go down there, Lowe's is usually better with regards to a variety of fittings.

what if you took a piece of 1" id tubing and then got some smaller tubing and then smaller and just put them inside each other over and over untill it fit. that is the easiest way. Honestly I would think 5/8" ID tubing would fit inside of 1" id tubing pretty snuggly depending on what type it is. If not, then there is surely a size between the two that will work. Also you can surely find an adapter from 1" to 3/4" tubing barb end to barb end and just get a small length of 1" tubing to connect the adapter. the 5/8" tubing will fit over the 3/4" barb fine.

Use heat to streach the tubing

5/8" to 1" stretch will make the tubing so brittle that it may and probably will break over time if not soon.

I just reduced mine. 1" to 3/4" to 5/8". Had to do it for my skimmer. You may be able to do the inner diameter thing and get one to fit in the other. If you do still use a hose clamp. They will come out once slimed up.

boy, I don't think I would trust a hose within a hose, even with a clamp, sounds like a disaster waiting to happen

HEat it up, it'll be fine.. As long as it's not the cheap Home Depot Vinyl tubing

I've done some insane things with tubing and it last a long time.

Ball value with 5/8 on one side and slightly bigger on the other and then raise it this way until you reach desired 1'
alot of plump work though for somthing so simple.

So far, I think stretching 5/8 tubing over 3/4 barb sounds like my best bet. This will mean I will have to find a 3/4 barb x1" barb adapter, or I will have to find a 3/4 barb x 1 1/4 inch barb /female threaded adapter, which I don't know exist.

By the way, the whole reason I am doing this is because the cheap plastic "adapter" that came with the skimmer broke one day while we were home and spewed water all over my carpet, I could not imagine the disaster if we were not home!!!!!
I think light escaping from the inlet of the UV can make any plastic/tubing brittle so I should use UV resistant hose.

I am also wanting to make my clear canister a little cheato fuge experiment. I was thinking keeping it contained in there with something to prevent it from blocking the output, and then shining a light on it from the outside and seeing what happens.
The fuge would be for nitrate reduction, not pods.

And I notice my skimmer works better with the UV running.

Anyway...anyone else have any good ideas?
