予備用 フィラーキャップ一式

Took a while to find this complete assembly, but once installed it clicked right into place and sealed perfectly—no more leaks during use.

Fits perfectly on my 303140 model and the cap seals tightly without any leaks. The plastic feels sturdy enough to withstand daily use. Exactly what I needed to replace the worn-out original.

The whole assembly arrived as one piece, so swapping out the cracked cap took me less than a minute without any fiddly bits to lose. It seats snugly against the rim with no wobble, which is exactly what I needed for that model 303140.
