Expansion Valve Seat Mushroom Shaped

It’s the tech support that is spectacular

The seal worked great. In fact, Sam included 2 different seals without being asked, in case the type of seal used by Izzo had changed the year my machine was produced. Just another example of the thoughtful, spot-on, and infinitely patient technical support I get whenever I email with a question about my machine. This

perfect fit (transparent now, not red)

Exact fit. no issue. With this new transparent seat, my OPV (expansion valve) whines/screams a bit now when the pressure ramps up.
