Key Features

• Package contains two (2) expansion plugs.
• Constructed from durable rubber with stainless steel screws and handles for corrosion resistance.
• Designed to fit openings ranging from 1.5 inches to 2 inches in diameter.
• Creates a watertight seal to prevent water from entering pipes during winterization.
• Wing nut handle allows for tool-free, manual tightening and expansion.

Replaces / Cross-Reference Part Numbers

• Universal replacement for winterizing plugs used in 1.5" to 2" pool plumbing fittings.

Compatibility & Fitment

• Suitable for both in-ground and above-ground swimming pools and spas.
• Fits standard 1.5" to 2" threaded and smooth-walled openings.
• Commonly used for skimmer inlets, return lines, and automatic cleaner lines.

When to Replace

• The rubber shows signs of cracking, hardening, or physical deterioration.
• A watertight seal can no longer be achieved, resulting in leaks.
• The metal components are heavily corroded or the threads are stripped.
• The plug is deformed and does not expand evenly when tightened.

Installation Tips

• Ensure the inside of the pipe or fitting is clean and free from debris before insertion.
• Insert the plug into the opening until it is seated firmly.
• Turn the handle clockwise to expand the rubber and create a seal.
• Hand-tighten only. Do not overtighten, as this may damage the plug or the pool plumbing.
• Check for a secure, leak-proof fit after installation.
