The Anderson Manufacturing 155E 1-7/8" Closed Extender Plug is designed to create a secure seal deeper inside plumbing lines where a standard expansion plug may not reach. Featuring a 6-1/2" extension between the rubber sealing surface and the wingnut, this plug is ideal for winterizing, pressure testing, and isolating plumbing lines in pools and spas.
Built for long lasting performance, each extender plug features solid rubber for a dependable seal, durable brass hardware, and a corrosion resistant plastic wingnut that is lightweight, easy to tighten, and designed to resist corrosion over time. Anderson extender plugs are engineered for repeated professional and residential use, providing reliable sealing season after season.
