Sold as a 2-pack, the kit includes one patch sized for 0.5-inch copper pipe and one patch sized for 0.5-inch iron pipe. Each patch features a self-adhesive backer, eliminating the need for glue or additional adhesives during installation. This product is commonly installed by plumbers during tub spout and showerhead rough-in or finish work where the pipe exits the wall surface.\u003c\/p\u003e\n\u003cp\u003eThe K820-20 is suited for residential plumbing applications where a pipe stub-out penetrates a wall in a wet area such as a bathroom or shower surround. The foam construction conforms around the pipe and presses flush to the wall surface, creating a barrier against moisture migration behind the wall finish. Typical installations include tub spout rough-ins, showerhead arm penetrations, and similar supply-line wall exits. The 2-pack format covers both copper and iron pipe stub-outs in a single kit, making it a practical add-on for bathroom remodel and rough-in jobs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClosed-cell foam construction resists moisture absorption and provides a reliable water barrier\u003c\/li\u003e\n  \u003cli\u003eSelf-adhesive backer allows tool-free installation with no glue required\u003c\/li\u003e\n  \u003cli\u003e2-pack includes one patch for 0.5-inch copper pipe and one patch for 0.5-inch iron pipe\u003c\/li\u003e\n  \u003cli\u003eDesigned for tub spout and showerhead stub-out applications in wet areas\u003c\/li\u003e\n  \u003cli\u003ePrevents water from migrating behind the wall finish at pipe penetration points\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned to fit 0.5-inch copper pipe stub-outs and 0.5-inch iron pipe stub-outs.
