備用完整填充蓋組件（適用於300302和300303）

I just installed this cap assembly and it clicked right into place on my 300302, perfectly snug. The seal feels more robust than the old one, and I’ve had zero drips after three uses.

Finally solved the leaking issue on my iron—this replacement cap fit perfectly on my 300302 model. The plastic feels just as sturdy as the original and clicks into place without any wobble.

The seal sits flush and the hinge feels sturdy when I open and close it, so no more steam escaping from the kettle. It took maybe a minute to swap out the old one on my 300303, and it fits exactly like the original did.
