Replacement silicone valve O ring for the Mash & Boil. This goes inside the Mash & Boil, behind the backnut. It also fits the recirculation elbow of the Mash & Boil with Pump. This O ring is 4mm thick, and 24mm outside diameter.
This also fits the Robobrew valve.

Q: Are the inner and outer gaskets the same?
A: Depends on the age of the unit. Older Mash & Boils had two valve gaskets, a small thin one on the outside, and a wider one on the inside. Current production only has a small thin gasket on the outside. We do not recommend removing the Mash & Boil Valve, as this can damage the seal.
