This Terra Incognita replacement cup is the original 18/8 stainless steel and BPA-free cap-cup component for the Bullet series vacuum flasks in the 500, 750, and 950 ml sizes. When the top cup of your flask is lost or damaged, this OEM part restores the seal and the drinking cup in one piece, threaded to match the specific Bullet volumes exactly. Built from rugged 18/8 stainless steel paired with food-grade plastic, it combines a durable outer with comfortable, safe handling, and it is offered in 100 ml and 150 ml versions to match the factory specification of your particular flask.
Made by Terra Incognita, a European brand with more than 18 years of expedition gear production, this cup keeps a good thermos in service instead of retiring it over a single missing part. It is the small replacement that saves a full flask.
Who is the Bullet Cup for?
This replacement cup is for owners of a Terra Incognita Bullet vacuum flask in the 500, 750, or 950 ml size whose cap-cup has gone missing or been damaged. Rather than replacing an otherwise perfect flask, you swap in the exact factory part and it works like new. Check whether your flask uses the 100 ml or 150 ml cup and order to match, since the two are sized to different Bullet volumes.
What is the Bullet Cup made of?
The cup pairs an 18/8 stainless steel body with food-grade, BPA-free plastic. The 18/8 steel, an established food-safe grade, resists dents and corrosion so the cup holds up to being knocked about in a pack. The plastic element gives a comfortable, safe surface for drinking and handling. Precise threading is the key detail, because it is what re-establishes the airtight seal a vacuum flask depends on.
Why choose the Bullet Cup over a generic cup?
A mismatched or generic cup rarely seals cleanly, and on a vacuum flask a poor seal means lost heat retention and drips in your bag. Because this is the original manufacturer component threaded for specific Bullet volumes, it seats exactly and preserves the flask's insulation performance. Buying the correct 100 ml or 150 ml version for your model is what guarantees that precise fit.

Bullet Cup FAQ
Which flasks does this replacement cup fit?
It fits the Terra Incognita Bullet series vacuum flasks in the 500, 750, and 950 ml sizes. As an OEM component it is threaded to match those specific volumes, so it seats and seals exactly where a generic cup would fit loosely and leak.
What is the difference between the 100 ml and 150 ml versions?
The two versions are sized to different Bullet flask volumes according to the original factory specification. Check which cup your flask originally used and order the matching size, since only the correct version threads on precisely and restores the airtight seal.
Is the cup BPA-free?
Yes, all contact surfaces use food-grade, BPA-free plastic alongside the 18/8 stainless steel body. That means no harmful chemicals leach into your drink, and both hot and cold beverages keep their intended flavor with no plastic aftertaste.
Why buy the original cup instead of a generic one?
The original cup preserves your flask's performance because its precision threading restores the airtight seal that vacuum insulation relies on. A generic cup that does not seal cleanly lets heat escape and can drip in your bag, defeating the point of the flask.
