Stainless still / steam-condenser lid with a 2" Tri-Clamp top port and a clear 3" PPSU sight glass — for brewing systems and kettles with a Ø340–355 mm opening.
Will it fit? One measurement decides. This lid seats on the kettle rim, so the only number that matters is your system's opening diameter — not its volume. It fits brewing systems and kettles with a Ø340–355 mm opening. Direct match: the BrewTaurus B40L Brewing System (Ø350 mm opening). Measure the inner rim of your kettle — if it's in the range, the lid fits.
The reinforced dished lid carries the weight of a pot still column or steam condenser — even mounted off-centre — without flexing, while the sight glass lets you watch the boil and make additions without lifting the lid.
Key points
- 2" Tri-Clamp top port — mounts a pot still, reflux column or steam condenser.
- 3" PPSU sight glass — keep an eye on hot-break and head off foam-overs in real time.
- Removable sight-glass disc — add hops or salts mid-boil through the port without removing the lid.
- Reinforced build — dished lid with two silicone handles for safe, stable lifting.
- Tight seal — extra-thick silicone gasket clamps leak-free.
What is PPSU?
PPSU (polyphenylsulfone) is a high-performance engineering polymer that stays clear and dimensionally stable to ~200 °C, shrugs off brewery acids and caustics, and takes impact far better than glass — so the sight glass won't craze or shatter on a busy brew day.
What's in the box
- Stainless lid Ø350 mm (2" TC top port · 3" sight-glass port)

Fit check: The opening decides — this lid fits Ø340–355 mm kettle openings (the B40L's is Ø350 mm). Volume alone doesn't determine fit: kettles of the same litre size come with different openings, so measure the inner rim of your kettle before ordering.
