PRO 用 O 型環套組（6 個 O 型環）

After months of daily use, my plunger finally started sticking, and these replacement o-rings were an exact match for the originals. The set even includes two spares for the plunger, so I’m set for a while.

The two plunger o-rings fit perfectly and the brew cylinder one sealed right up—no more leaking when I press down. I've only used one set so far, but having six backups means I'm set for a good long while.

My old o-rings were so worn the plunger kept sticking mid-press, but these six replacements cover everything I need for my PRO. The brew cylinder one seated perfectly on the first try, no fussing required.
