زجاج عازل مع حلقة مانعة للتسرب، فضي، 1.00 لتر لـ 3591/3592/3598/3599

Replaced the old broken glass in my 3592 flask and it fits perfectly with the sealing ring snug. Keeps my coffee hot for hours like it did when new.

The sealing ring fits perfectly and the glass keeps my coffee hot for hours, just like the original. I was relieved to find this exact replacement part without needing to buy a whole new flask.

After my old glass cracked I wasn't sure this would fit, but it screwed right into my 3598 with zero leaks. The sealing ring sits tight around the rim, so my coffee stayed hot through a whole morning of errands. Genuinely relieved I didn't have to toss the whole flask.
