Frozen pool pipes can mean thousands in repair costs when winter hits. These commercial-grade rubber expansion plugs are your first solution against freeze damage. Simply insert into skimmer lines and return jets to create watertight seals that block ice formation all season. Made from industrial-strength rubber that expands perfectly to 1.5in openings, they endure repeated seasonal use without cracking. Beyond winterizing, use them for leak detection when pressurizing lines or as temporary stoppers during equipment maintenance. Includes 2 plugs with weatherproof construction - a small investment that stops catastrophic pipe bursts when temperatures plummet.
