GORTEF supplies PTFE sealing bands to fit the Doboy B-555, made to the dimensions you measure off your own machine. It is an aftermarket replacement rather than a genuine Syntegon Technology (formerly Bosch Packaging) part.
The B-555 is a continuous band sealer in the Doboy B series. The bands take every cycle the machine runs, which is why they are the most frequently replaced part on it.
Confirming the Exact Specification
Tell us what you are replacing and we will match it. Send the dimensions of the band you are removing, or a photo of it alongside its packaging, and we will confirm the construction before you order. Measure the old band laid out flat rather than on the machine, and check the width at the seam as well as along the run.
How to Order Bands for the Doboy B-555
Measure the band across its width and right around its length. PTFE sealing bands are made endless to the length you measure.
Band sealers run their bands in pairs, so tell us whether you want a single band or a full set for a changeover.
