Replaces / Cross-Reference Part Numbers

When to Replace

• The rubber shows signs of cracking, brittleness, or has become permanently deformed.
• A watertight seal can no longer be achieved, resulting in leaks.
• The screw threads are stripped or corroded, preventing proper tightening.

Installation Tips

• Ensure the inside of the pipe or fitting is clean and dry before insertion.
• Insert the plug into the opening to the desired depth.
• Turn the screw clockwise to expand the rubber plug and create a seal.
• Tighten until the plug is snug. Do not over-tighten, as this can damage the plug or the pool fitting.
