標準キャップ

My old cap cracked after years of use, and this one sealed the deal on my water tank without any fuss. The threading is clean and it fits my large port snugly, so no leaks when I tip it around. Exactly what I needed.

This 2.25-inch cap threads on perfectly without any leaks after a week of daily use, and the fit is snug enough that I forgot it wasn't the original. It's a no-fuss replacement that does exactly what it should.

After wrestling with a cracked cap all summer, this one clicked into place on the first try and seals tight without any fuss. The threading is clean and the 2.25-inch fit is exactly what my tank needed.
