    Vintage Everlast red plastic bladders

    Has anyone been able to use the large 4233 vintage red plastic bladder inside a large bag? I have two of these bladders, and they don't inflate anywhere close to filling the 4205 or the 4207. The best I can do is put them in the 4213.

    They seem to have a slight elasticity to them, but nothing like latex. I'm afraid I'll pop them trying to go for the larger bags.

    If this is the bladder the that the label says it fits the 4205 and 4207, yes they should. Both Paranday and myself have them in our 4205's. The supply appears to be gone now, not seeing any new old stock on these anywhere now. My 4207's now have the Title large bladders in them now

      How much do they stretch before bursting? The label did indeed say large / 4233, but it does not seem to come close. I didn't put the gauge on, but they were rock hard and no bigger than a 4213 bag.

        They stretch quite a bit. The secret is that you just inflate a little bit at a time, don't try to do it all at once. When they were new (and fresh) you could inflate it in one sitting. Thing is we really don't know what the shelf life of these bladders are. Obviously longer than a latex bladder. I've had those that have been sitting in a closet turn to goo for a while. If the red plastic bladders are going to fail, it's been proven that 99.9% of the time it's going to be at the seam. There tended to be a problem with that process in the production, probably the reason they went back to rubber/latex.
