Key Details
| Detail | Verified information and buyer relevance |
|---|---|
| Product type | Replacement fuel cap for a lawn mower petrol tank. |

| Included quantity | 1 cap, which suits a direct replacement rather than a multi-part repair. |
| Dimensions | 5.5 x 5.5 x 2.2 cm. This helps with fit and handling checks. |

What to Compare Before Buying
- Thread size: Match the stated 45 mm inner thread to your tank opening.
- Model compatibility: Check the exact mower model against the listed AL-KO and Loncin fits.
- Quantity: This is a single replacement cap, not a cap set.
- Dimensions: Compare the 5.5 x 5.5 x 2.2 cm size if space around the filler neck matters.
What Else You May Need
Only the cap is named here, so make sure the rest of the fuel tank assembly is already in good condition before replacing it.
Before You Decide
Confirm the 45 mm inner thread, the exact mower model and the single-cap quantity before choosing an offer. If your machine uses a different tank thread or a different fitting format, this replacement will not be the right match.
