Sipromac Vacuum Sealer Replacement Parts: What to Know Before You Order

If your vacuum sealer's nameplate reads Sipromac, you may have noticed that a lot of the replacement parts online are listed under the Berkel name instead. That's not a mistake — Berkel acquired Sipromac, and the Model 350/350D, 420A, 550A, 600A, and 620A chamber sealers are the same machines regardless of which name is on your unit. This guide covers what's genuinely Sipromac-specific, what's shared with Berkel, and how to make sure you order the right part the first time.

Parts That Are Sipromac-Specific

A handful of parts are listed under the Sipromac name only, most notably the 2.5mm concave seal wire — a different profile from the flat wire used on other models, so it's worth double-checking which shape your existing wire has before ordering. The Model 350 seal bar assembly is also listed under the Sipromac name.

Parts Shared With Berkel

Most other components — seal wire in other profiles, lid springs, seal bladders, control boards, and gaskets — are the same part regardless of which name is on your machine, and are listed as "Sipromac/Berkel" for that reason. These include:

For control boards and keyboards specifically, check the Berkel parts collection — the MC-30, MC-40, KB-30, and KB-40 components apply to both names equally.

How to Confirm You're Ordering the Right Part

Because the same physical part can appear under either brand name, matching by name alone isn't reliable. Before ordering, gather:

  • Your model number (350, 350D, 420A, 550A, 600A, or 620A)
  • Whether your nameplate says Sipromac or Berkel (both are fine — this just helps us confirm compatibility)
  • The part you're replacing, including any visible part number
  • The seal wire profile if that's what you're ordering — flat, concave, or double-seal, since these aren't interchangeable

Signs a Sipromac Part Needs Replacing

  • Seal looks weak, wrinkled, or inconsistent
  • Lid doesn't hold firmly under vacuum
  • Vacuum reading is lower than expected
  • Control panel loses saved programs or won't respond
  • Visible cracking on gaskets or seal bar rubber

Shop Sipromac Replacement Parts

Once you've confirmed your model and part, browse the full Sipromac parts collection, or check the Berkel parts collection for control boards and keyboards. If you're troubleshooting a specific sealing problem rather than just restocking parts, our Berkel & Sipromac troubleshooting guide walks through common causes by symptom.

Conclusion

Not sure whether your machine is technically a Sipromac or a Berkel, or which version of a part you need? Send us your model number and we'll help confirm before you order — it's a quick way to avoid ordering the wrong seal wire profile or lid spring.
