This is a brand new 6" conflat welded bellows that we bought for a project that fell through prior to our installing this piece. Consequently, it was never opened and so is pristine. (See photo) It is made by MDC vacuum, with a welded bellows with a 3 1/2" inside diameter and is 7 1/2"long with a 6" free bellows length.

For sale is a used vacuum bellows, with a port 1.25" diameter on top and a 1/4" thick flange on the bottom. The drawing that is posted shows most of the specs, except that the bottom flange was changed from a rectangle to a circle of 4.0" diameter. We paid over $800 to have this custom-made for a machine which is no longer in use.

From the unneeded/unused parts bin, here's a stainless steel 48" vacuum hose with KF16 fittings. The only reason the plastic is cut on the packaging or the foam wrap was pulled back was so I could take photos of the ends for this auction -- otherwise, the caps have never been removed nor has this hose been used. This is not a braided hose -- I believe the construction is referred to as bellows.
