The genuine factory Sight Glass Replacement Kit for the Steamaster HPJ-2S and HPJ-2 steam cleaners is a complete kit that includes every component required for a proper, compliant sight glass replacement. The "S" in HPJ-2S designates the solenoid model. Steamaster no longer supplies the rubber gaskets separately from the sight glass kit, making this complete assembly the correct service solution.
To meet ASME safety standards for pressure vessel maintenance, the sight glass must be replaced any time the gaskets show wear or deterioration — the glass and gaskets must always be serviced together.
