Seal it tight. Brew clean.
The extra-thick flanged silicone gasket that seats the PPSU disc in a 3" sight-glass assembly. The flange wraps the rim of the disc, so the band clamp compresses silicone — not plastic — for a leak-free, sanitary seal that also protects the disc. Direct replacement for the gasket supplied with our Sight Glass Steam Condenser Lids, and the seal you need when building a sight glass onto a K40 / K80 / K220 Dome Lid.
Key points
- Flanged profile — holds and cushions the 3" sight-glass disc; no glass-on-metal contact.
- Direct replacement — the same seal shipped with the Ø350 and Ø400 Sight Glass Lids.
- Food-grade silicone — high-temperature, boil-proof, flavour-neutral.
