Before you buy
Make sure this is the part you need.
Accessory products are often model-specific. A similar-looking bottle, key, pump head or seal ring may not fit every diffuser.
Step 1
Check your model
Look at the diffuser body, product page, order history or product manual to confirm the exact model.
Step 2
Check the part type
Confirm whether you need a bottle, key, pump head, pump core or seal ring before ordering.
Step 3
Check compatibility
If the product title lists a model pair, such as OV-3 / ND-500 or Pro-300 / OV-10, only use it for those compatible models.
Care tips
Keep your scenting system easy to maintain.
Small replacement parts help keep the diffuser routine clean, convenient and consistent. Handle accessories carefully and replace worn parts when needed.
Keep spare bottles clean
When rotating oils, use clean bottles and avoid mixing old fragrance residue with a new scent.
Do not force parts
If a part does not fit easily, stop and confirm compatibility before applying pressure.
Use manuals when unsure
Check the product manual or contact support if you are unsure how to replace the part.

Accessory buying questions.
Use these quick checks before ordering a replacement part.
How do I know if this part fits my diffuser?
Check the product title, model badge and your diffuser model name. If the product lists a specific model or model pair, use it only for those compatible models.
Can I use this part for a different JCLOUD model?
Not always. Many accessory parts are model-specific. Bottles, keys, pump heads, pump cores and seal rings may have different sizes or connector designs.
What should I do if I am unsure?
Contact support before ordering. It is better to confirm the correct part than to buy a part that does not fit your diffuser.
Is this product a diffuser oil?
No. This is an accessory or replacement part. If you need fragrance oil, visit the 100ML Oils or Refills collection.
