Description
A Tired Gasket Ends Every Steam Session Early
Steam pressure is the whole point of a Bellman stovetop machine, and it only builds if the tank seals completely. Once the original rubber hardens or cracks, that pressure escapes at the seam long before your milk is textured — the Bellman tank gasket (G70) is the fix.
Same profile, same rubber compound, same fit as the seal your machine shipped with.
Why this gasket matters
- Restores full steam pressure inside the tank
- Stops hissing and leaking at the tank-to-boiler joint
- Genuine Bellman replacement part, not a generic substitute
- Simple swap — no tools, no soldering, no technician visit

Bellman Tank Gasket — FAQ
How do I know my Bellman tank gasket needs replacing?
Look for hissing at the tank seam, slow steam build-up, or visible cracking and hardening on the rubber ring.
Does this gasket fit every Bellman model?
It fits the Bellman Cappuccino and Espresso Coffee Maker tank assembly under part code G70. Check your machine’s tank fitting before ordering.
Do I need a technician to install it?
No. The gasket sits in the tank rim and can be swapped by hand in a few minutes — no tools required.
Is this a genuine Bellman part?
Yes. It’s listed as an original spare part, not a generic aftermarket rubber seal.
How long does a tank gasket usually last?
Life varies with usage and cleaning, but rubber seals on stovetop steamers typically need replacing every year or two of regular use.
