Threaded winterization plug 1½″ with O-Ring – Feherguard (yellow)

The Feherguard threaded winterizing cap is the simple and reliable solution to protect your skimmer during winter. It screws directly into the bottom of the skimmer to block the return line and prevent water from entering.
Its new version features a robust O-Ring that creates a 100% airtight seal, limits leaks, and maximizes freeze protection. Color high visibility yellow, easy installation and reusable use season after season — an improved alternative to the traditional Gizmo.
