Hario Replacement Glass Top – Coffee Syphon Technica 600 ml (TCA-5)
At the top, above the flame, sits the upper globe where the real performance happens: the water rises, the coffee steeps in the pale brew, and as the heat fades, everything settles back down, clear and calm. This glass globe is the stage for the whole Technika.
It sits directly above the heat source and goes through heating and cooling with every brew – over time, one reason why this particular glass eventually wants replacing.
Where extraction happens
In the upper globe, hot water meets the ground coffee, and this is exactly where it's decided how clear and aromatic the cup turns out. A clean seal on the lower glass bulb is essential for building the pressure that creates the vacuum – and with it, the flow back through the filter.

Who it's for
For anyone with a Hario Technica 600 whose upper glass has cracked or broken. The lower glass bulb and the burner stay untouched and keep working independently.
What goes with it
A medium grind suits the syphon best – if you want affordable and precise grinding, the Comandante C40 or the Varia VS3 from our coffee grinder collection deliver that; if you want more, the Weber Workshops EG-1 or the Option-O Lagom does too. For dosing, scales from the Normcore range fit well, compact and reliable, or with app connectivity from the Acaia collection. Aromatic beans like Nutty Delight round off the clear syphon cup.
Frequently Asked Questions
Does the glass also fit the Sommelier or the NEXT?
No, the upper glass is made specifically for the Technica 600 (TCA-5). The Sommelier and NEXT have their own replacement glasses.
Can I replace it myself?
Yes, the upper glass fits onto the lower glass bulb without any tools.
Is the filter included?
No, this spare part only includes the upper glass. Replacement cloth filters are available separately in our Hario collection.
Can I see the product before buying it?
Our showrooms in Bern (Gerberngasse 44) and Zurich (Hagenholzstrasse 50b) show a wide selection, but not our entire range – the display changes. Drop us a quick line at [email protected] before your visit, and we will check whether the product you have in mind is currently there.
Roastery Tip
The clear, full syphon cup pairs beautifully with the round notes of Nutty Delight or, for maximum body with no acidity at all, Very Nutty. If you like it fruity, discover Wild Peach. That's our recommendation, one of many.
