Please note: 747 Stopper Plugs have passed IP66 compliance tests to IEC 60529 with no additional sealing. However CMP would recommend the addition of thread sealant or grease (such as Dow Corning No. 4 Silicone) in order to help maintain IP66 and keep water out of the enclosure in the long-term. The addition of thread sealant or grease is permitted as long as it is non-setting, non-metallic and non-combustible in compliance with IEC 60079-14.
