6.5" Bands?

[masterof0]

So I just got some LP45 tanks back from hydro and the bands that were originally on them were rusted through so they were trashed. Now that I have them back, I measured the tanks and they appear to be 6.5" tanks. 5.5, 6.9, etc seem to be common sizes, but I have not been successful in finding any 6.5" bands. Does anyone know where I can find some bands this size?

I bought a set of Rick Green bands for a pair of Al 50s

I don't remember whether it was the bands or the cotton harness that came with pieces of rubber and instructions to use them if the bands were too loose.

If you can't find 6.5" bands, you might consider putting a piece of rubber between the band and the tank.

Are you sure that they aren't 5.5" diameter? All of the LP45s that I have seen are 5.5".

What is the center to center spacing of your manifold?

They are older cylinders and based on what people have told me, they not "traditional" cyliders but have been possibly converted possibly from aviation. I am taking the word of the previous owner that they are 45s, but they are 6.5" diamer and 1800 psi, so that would lend itself to a similar volume.

Yes, it sounds like you will need custom bands. You will also need to know the center to center spacing of your manifold to have them made.

If ya want a set of vintage 6.9" bands on a backpack let me know. I'd would give them to you for free, just pay for the postage. As said you would probably need to put some spacers between the cylinders and bands but many did that anyways.
