Evans Components PCW Regulator Leakage on Stem/poppet, proprietary wet-ted surface treatmentPWEA®to prevent stress corrosion cracking for PCW applications.

Through the process of continuous product improvement Evans Components decided to begin treating all of our PCW regulators with a PWEA® treatment. This new process eliminates the potential dezincification of brass wetted inter-nals which in some cases has caused leakage around the stem/poppet due to stress corrosion cracking.
