Integrity Products Drain Plugs

Integrity Drainplug
Used alongside metal jacketing and caulking/sealants, the Integrity Products Drainplug provides extra protection against corrosion under insulation (CUI). Made with flame-resistant, non-combustible Polyphenylene Sulfide Black (PPS), Integrity Products Drainplugs allow any water or moisture that penetrates the insulation system to drain out freely.
