Sipromac & Berkel Vacuum Sealer Parts

Sipromac and Berkel share parts across much of their chamber vacuum packaging line, but not universally — model number still matters. This page brings together the most commonly needed replacement parts for Sipromac and Berkel machines, including models 350, 350D, 420A, 600A, and 620A.

Control boards and keypads

Control boards come in two families: MC-30, paired with the KB-30 keypad, and MC-40, paired with the KB-40 keypad. These are matched pairs, not mix-and-match. If your MC-30 board won't hold its settings, that's typically a memory battery issue rather than a board failure.

Lid springs

Lid springs are specified separately for the 350/350D, 420A, and 600A/620A models — confirm your exact model before ordering.

Seal bladders and seal wire

Seal bladders differ by model: the 420A uses a smaller bladder than the 550A/600A/620A line, and quantities per machine vary (the 550A needs two, the 600A/620A need four). Seal wire is available in several profiles — 2.5mm flat, 2.5mm concave, 8mm double seal, and T-profile cut-off — so confirm which profile your seal bar uses before ordering.

A note on Berkel builds

Not every machine sold under the Berkel name was built by Sipromac. Webomatic-built Berkel machines use a different seal wire combination (4mm concave paired with a T-profile cut-off wire) than the standard Sipromac-built Berkel sizes above — worth confirming which company actually built your machine before ordering seal wire.
