Rubber Plug #4 for Closing | PLUG4

The AquaFab #4 Rubber Plug (PLUG4) is a closing fitting that seals an opening in your pool system during winterizing. The rubber expands as you tighten it, forming a watertight seal that blocks water and debris. Perfect for pool owners who close their pool every fall.

Features

• Material: weather-resistant rubber
• Model: #4 (PLUG4)
• Type: expandable closing plug
• Reusable season after season

How to use

Insert into the opening you want to seal (return line, skimmer or fitting) before winter. Tightening expands the rubber and locks the plug in place. Remove tool-free in spring.

When to replace

Replace once the rubber cracks, hardens or no longer holds a seal.
