There are actually 3 of those brass plunger things. Two at the bottom and one at the top. Mine were all cooked, so I'd guess if you need 2 you will need all 3.
The other thing to get are the brew axle sealing gaskets. The brew lever attaches the the axle, the axle goes into the grouphead and turns a cam that pushes the plunger things against a spring. There are rubber seals that prevent brew water from leaking out. Finally, the bestest upgrade ever for the brewtus is a silicone portafilter gasket. Get the 8.5mm from cafelat, on amazon for like $7. They last forever. Make sure when you install that number on gasket faces up to screen. On Tuesday, August 3, 2021 at 3:32:23 PM UTC-7 HowardG wrote: > Thank you for your response.
