Solo DF64 調整環和蓋子 O 型環

The adjustment ring has a nice, solid feel when turning, much better than I expected for a simple replacement part. The O-ring seated perfectly into the groove on my grinder's cap, so no leaks during use. It’s exactly what I needed to get things back to normal.

The O-rings fit perfectly on my grinder's adjustment ring and cap, a nice snug seal that stops any coffee grounds from migrating. I finally don't have to clean that annoying dusty residue off the counter after every use.

The replacement adjustment ring fits the Solo DF64 well, though I wish the O'ring was a bit thicker to match the original. It’s a simple part swap that got my grinder working again without issues.
