Feherguard yellow winterization plug 1½ in with O-ring

The Feherguard 1½ in. threaded winterizing plug is designed to effectively protect skimmer plumbing when closing the pool. It screws directly into a 1½ in. threaded fitting to help prevent water from entering the line during the winter.

This version features a durable O-ring that improves the plug’s seal and helps reduce the risk of leaks. Its high-visibility yellow color also makes it easy to locate when opening the pool in the spring.

Reusable from season to season, it is a simple and practical solution for winterizing above-ground and in-ground pools equipped with a compatible fitting.

Improved Sealing with O-Ring

The integrated O-ring creates a tighter seal between the plug and the skimmer fitting.

This design helps to:

• Prevent water from entering the line
• Reduce the risk of leaks during the winter

• Simplify the seasonal closing of the pool
