The ratchet clamps (and all of our plumbing) are all rated in nominal sizes. This doesn't refer specifically to either the ID or the OD but the plumbings nominal size. Nominal size is the standardized sizing in plumbing (just like if you went to home depot, etc) so that you know a 1" pipe will fit a 1" union, which will fit a 1" barb, which will fit 1" braided nylon tubing with the help of a 1" ratchet clamp, though the ID/OD of none of these components actually measures 1" If you have a 1" barb with 1" braided nylon tubing connected to a 1" pipe, pump, etc then you would want the 1" ratchet clamp.
We use nominal ratings for our plumbing and fittings, so if you are using standard braided vinyl tubing in 3/4", you'll want a 3/4" ratchet clamp.
Have a great day!
You will need the spigot x barb adapter to connect to 3/4" tubing. If the tubing on the reefer tank is 1' soft tubing you will need to increase the output from 3/4" on the vectra and we recommend using the Vectra adapter kit along with the larger spigot x barb adapter to do so! I have included both options below!

All of our ratchet clamps and plumbing is listed in nominal sizes, so if you have 1/2" nominal tubing you would want the 1/2" ratchet clamp.
Ratchet clamps are used to secure Braided Vinyl tubing to barbed fittings. If you are using silicone or traditional thin wall tubing we highly suggest measuring the outside diameter of the tubing you will be working with to select the correct ratchet clamp.

Don't have to worry about falure do to rust By Rick on 2/23/2017Rick would recommend this product to a friendHad used hose clamps for original setup three of eight failed do to rust the hose stayed in place without them but for peace of mind purchased the Ratchet clamps. The 1 1/4" closed tight around the braded vinyl tube and didn't bottom out the 3/4" bottomed out and could still be twisted around the tubing I don't think it will be a problem but wished it was tighter.
Not for Hose's By Matthew on 1/27/2017Matthew wouldn't recommend this product to a friendI bought this for my Aqueon sump setup. This 1" clamp did not fit my 1" plumbing. The hose I used was plastic and not vinyl. This may work for vinyl tubing but as stated in other reviews this will not work for all 1" standard plumbing. I will try to buy another size and update my review.
Titanium Clamps Much Better By Jesse on 1/2/2017Jesse wouldn't recommend this product to a friendThese plastic clamps are ok if used out of saltwater and not off a pump. I would also recommend doubling up if you're placing them on a pump. The thing is that after a random amount of time in saltwater they just get brittle and snap. They work better for something like a UV Sterilizer connection that's out of the water, for example.
But any clamp that's on a submerged pump I use Titan Titanium clamps. They're more expensive, but don't rust while submerged in saltwater like the "stainless steel" clamps do. I also double up on the Titans as well if they're on a pump because I had a hose pop off a pump once (with plastic clamps) and just shot water everywhere, flooding the basement room.
So under water use metal and it has to be Titanium if you don't want rust.
Strong and easy to use By Knuckledragger on 3/16/2016Knuckledragger would recommend this product to a friendI only gave four stars as it seems that these could be a bit wider to cover more area on the hose for compression. They do work though and are very easy to use.

Better than expected By don_chuwish on 1/18/2016don_chuwish would recommend this product to a friendThese are much more substantial than I'd expected. They feel tough and really seem up to the task.

Work Great By Russ K. on 7/2/2015Russ K. would recommend this product to a friendThese work great! I love that you can actually get them onto existing tube without having the disconnect the tube - they can open over and around the tube. I did notice a few negatives in other reviews, so I wanted to provide some tips.
For tightening I use Channel Locks. You can easily set them to get the best grip when tightening the clamp. I go until I think it's tight, then I see if I can get one more click.
For removing them - because there are multiple interlocking layers of teeth, you can't simply pry it. So instead of trying to pull the clamp open (pulling outward left and right), I actually grab each end and push one up and one down. Basically its as if you want to change the shape of the clamp from a circle around the tube to a spiral. Once you push the teeth enough so that they are no longer inside each other, it opens very easily.
Good By Turf on 4/9/2015Turf would recommend this product to a friendI wouldn't say they are as good as a metal clamp for tightening but they don't rust.which made them better in my mind. Worked well for two years, just had to go and reclamp them tighter after awhile which is normal for metal too.
Negative... good luck getting it apart if you need to. I'd suggest just having a few extra on hand and cut the old one off.
good clamp but limited range By Bruce on 3/18/2015Bruce would recommend this product to a friendBought these to use with the soft silicone tubing. They don't cinch down far enough to tighten up on it. They will probably work well with reinforced vinyl tubing that is thicker walled.
...good clamp if you have tubing in a relative size, I had to get out the old zip ties.
