Lid Set (White) for SU-BA36/48: Replacement Signs and Fit FAQ

What this lid set is, and what the name tells you

The Lid Set (White) for SU-BA36/48 (-WM) Cocoon White is a replacement part for Zojirushi's Cocoon White bottle line. The model numbers in the name are your first fit check: the set is identified for the SU-BA36 and SU-BA48, and the (-WM) suffix ties it to the Cocoon White finish. If your bottle's model number matches, this is the part to compare against your old lid.

The supplied product record lists the set at USD 11.70, with a catalog comparison price of USD 19.50. Beyond the model fit and the color, the record does not supply lid dimensions, materials, or assembly steps — so this FAQ sticks to what is confirmed and tells you where to verify before ordering.

Fit and compatibility questions

Which bottles does this lid set fit?

The product name identifies it for the SU-BA36 and SU-BA48 in the Cocoon White (-WM) finish. Check the model number on your bottle before ordering; the supplied record does not list any additional compatible models.

Is this the same as a Zojirushi mug lid set for other models?

No. The part is named for the SU-BA36/48 series and the Cocoon White finish. A lid set for a different mug or bottle family is a different part, even if it looks similar. Use the model number in your bottle's base or documentation as the deciding check.

Does the white color match my bottle?

The set is specified as White for the Cocoon White (-WM) version. The supplied record does not describe shade matching beyond that name, so treat the (-WM) designation as the color confirmation.

What comes in the set?

The record calls it a lid set but does not enumerate individual components, dimensions, or materials. If you need to confirm a specific piece inside the lid assembly, check the packaging or contact the store before ordering.

When to replace the lid instead of cleaning it

How do I know my mug lid needs replacing?

The supplied record does not include replacement criteria, so there is no official checklist to copy. A practical approach is to compare your lid against how it performed when new: if the lid no longer seats the way it used to, or cleaning no longer brings it back to usable condition, a replacement set is the straightforward fix. Avoid guessing at causes the record does not confirm.

Can I replace just the lid and keep the bottle?

Yes — that is the purpose of a replacement lid set. The bottle body and the lid are separate, so a worn or damaged lid does not mean replacing the whole bottle. Confirm the model fit first, then order the set.

Should I buy a spare before the old lid fails?

That is a reasonable choice if the bottle is in daily use and you want to avoid downtime. The catalog price of USD 11.70 against a comparison price of USD 19.50 makes a spare easy to justify. The record does not state a shelf life, so store it clean and dry.

• Lid Set (White) for SU-BA36/48 (-WM) Cocoon White: WARNING: This product can expose you to chemicals including nickel, which is known to the State of California to cause cancer. For more information go to www.P65Warnings.ca.gov. This is the only safety information supplied for the part. Read it before purchase if California Proposition 65 warnings matter to you.

The nickel warning, explained plainly

Why does a lid set carry a nickel warning?

The supplied record includes a California Proposition 65 notice stating the product can expose you to chemicals including nickel. The record does not specify which component contains nickel or under what conditions exposure occurs, so the warning should be read as supplied — a required disclosure, not a description of everyday use.

Does the warning mean I should not use the lid?

The record does not make that claim, and it would be wrong to infer one. Proposition 65 warnings are disclosure requirements; the supplied information does not include a use restriction. If you have a specific nickel sensitivity concern, treat the warning as a reason to ask the store or your physician rather than a reason to assume the product is unsafe.

Before you order: a three-check routine

1. Read the model number off your bottle: Look for SU-BA36 or SU-BA48 on the bottle base or in its documentation. The lid set is identified for those two models in the Cocoon White (-WM) finish.
2. Match the finish: Confirm your bottle is the Cocoon White version, since the set is specified as White for (-WM).
3. Decide whether you are replacing or stocking a spare: If the current lid still works after cleaning, a spare is optional. If it does not, order the replacement set rather than a whole new bottle.
