Plumbing help

[saullman]

I am in need of some plumbing help. I am soft plumbing my Vectra S1 pump to my Reefer 350 tank. I know this scenario won't apply to most of you because you have different equipment and/or newer equipment. However, someone must have come across this same problem before. Here's the problem.

The barb on the Red Sea return connector will take 5/8" inner diameter tubing.
The barb on the Vectra S1 pump is larger at 3/4" inner diameter tubing.

How can I make these 2 work together so I can finally fill my tank up with water?

Need a barb reducer like this

Yep, use a barb reducer. Then run the appropriate size line on each side.

Either use 5/8 Id, heat gun/hair drier on tubing will soften it enough to get on 3/4 barb.
Or use 3/4 Id, and use a short (one inch) piece of 5/8 tubing on 5/8 barb, then push 3/4 tubing over that

Mclendons. Lowes. Home depot. Should sell the correct size barb fitting with the correct size fit up to match the other one. Hths

I'm not sure if its a bad idea, and I'm sure someone will chime in if it is, but could you possibly heat up some 5/8 tubing and force it over the 3/4 barb?

I like your idea the best. Do you know if I would be able to buy this part at Lowe's or HD?

I have received quite a few suggestions like yours so it can't be that bad.

Yea I saw it was posted while I was typing. I don't see what it would hurt to at least try. I've forced the wrong size tubing onto barbed fittings before, although none I did were that large.

I found one at HD, but it's brass. Can I use brass or stick to plastic?

 

[monkeyCmonkeyDo]

Plastic only...

I tried looking for these on their website, but no dice. I do remember seeing some reducers last time I was at my local HD. but I don’t remember the size.

Both stores sell them, but only in brass.
