The Anderson Manufacturing Closed Brass Hook Expansion Plug is designed to create a secure seal inside 1-1/2" pool and spa plumbing lines during winterization, pressure testing, and plumbing maintenance. Its 1-1/2" extension between the rubber sealing surface and wingnut allows the plug to seal past threaded fittings in return lines, main drains, and other plumbing applications where a standard expansion plug may not provide the ideal sealing position.
The integrated brass hook handle features a right-angle bend that makes installation, positioning, and removal easier, especially in hard to reach plumbing openings. This design provides added control when tightening the plug while helping create a dependable, leak resistant seal.
Constructed with a solid rubber expansion body, durable brass hardware, and a heavy duty corrosion resistant plastic wingnut, this plug is built for long lasting performance and repeated use. Its reliable sealing design makes it an excellent choice for both professional pool service technicians and homeowners performing seasonal maintenance.
