Rubber Pool Plugs (1 Inch, 1.25 Inch, 1.5 Inch)

Key Features

• Set includes three expansion plugs in common pool plumbing sizes: 1 inch, 1.25 inches, and 1.5 inches.
• Constructed from durable black rubber for a secure, watertight seal.
• Features stainless steel hardware (bolt and wing nut) for corrosion resistance.
• Designed to prevent water from entering pipes during winter, protecting them from freeze damage.
• Simple hand-tightening mechanism expands the rubber to fit securely inside the pipe.

Replaces / Cross-Reference Part Numbers

• 1" Plug: Replaces standard size #5 winterizing plugs.
• 1.25" Plug: Replaces standard size #7 winterizing plugs.
• 1.5" Plug: Replaces standard size #9 and #10 winterizing plugs.

Compatibility & Fitment

• Designed for use in standard 1", 1.25", and 1.5" pool fittings.
• Commonly used to plug skimmer lines, return lines, and automatic cleaner lines.
• Suitable for winterizing most in-ground and above-ground swimming pools and spas.

When to Replace

• The rubber is cracked, hardened, or no longer pliable.
• The plug fails to create or maintain a watertight seal, resulting in leaks.
• Hardware is rusted, corroded, or the threads are stripped.
• Visible deformation or damage prevents a proper fit.

Installation Tips

• Ensure the water level in the pool is below the fitting to be plugged.
• Clean any debris from the inside of the pipe or fitting opening.
• Insert the plug into the fitting until it is seated firmly.
• Hand-tighten the wing nut clockwise. This will compress the rubber, causing it to expand and seal the pipe.
• Continue tightening until the plug is snug. Do not over-tighten, as this can damage the plug or the pool's plumbing.
• Verify that no water is leaking past the plug after installation.
