Corrosion around fitting

Is this due to the incorrect material? Or do I need to look into something else. This is a Burnham ES2 boiler, and is about 2 years old.

Thanks,
Justin

    If I was a betting man, I'd say that Chinese fitting has been leaking for a long time due to bad threads.

    Single pipe quasi-vapor system. Typical operating pressure 0.14 - 0.43 oz. EcoSteam ES-20 Advanced Control for Residential Steam boilers. Rectorseal Steamaster water treatment

    Cool. I didn't want to buy the same parts and it happen again. I try to check the boiler and piping every six months for stuff like this. Guess I should have checked sooner and harder.

    It may have leaked from day one. Often times a connection like that leaks when the system is cold, and stops as it heats up.

    It will be a bit of a project to replace, judging by the tight connection nipples and fittings.
