Is a 1" Barb, 1" PVC Pipe, 1" Bulkhead all the Same?

[Asonitez]

So recently I purchased Bulkheads that had barbs on them already. They are 1" Bulkheads

I then Bought a 1" compression fitting for my Vectra L1

I then bought a 1" Extra Barb's for my CPR Filter Sock Holder.

The Crown of the entire project was purchasing the 1" ID Black tubing.

The thought process is that the 2 1" Drains will drain from the tank (Herbie Style) 1 Primary 1 Backup Emergency. The Vectra L1 will pump water back into the tank.


The Problem -


The VECTRA L1 compression fitting to the 1" Slip X Insert Works GREAT.
The Hose to the 1" bulkhead however DOES NOT. IT won't slide over the barbs without some elbow grease and a cup of hot water. I believe these barbs were probably meant for the Eshops style type of Overflow. The Corrugated kink Free Pipes.

I'm cool with using the 1" hose but I want to make sure that I'm not hindering my tank by using that tube. Can I reasonably expect the exact same flow through the Barb/Bulkhead/Tube if they are ALL 1" ID??

A good hose fit over a barb should be very difficult to get the proper fit. I usually have a pot of boiling water on hand for the job, although silicone lubricant helps too. Even then, it still takes a lot of elbow grease, so your observations are correct. Regarding flow, tubing is more restrictive than piping, but for the purposes of our tanks, it makes little difference. Your flows should all be the same.

FWIW, the braided vinyl tubing is the most difficult to work with. The soft black vinyl tubing is the easiest. I am not familiar with the tubing you posted the link for but that looks like what some people use for their drain lines - I do not think that is a good tubing for aquarium use as those ridges will cause pressure loss and capture detritus.
