C9 Socket Seal

100 Pack

Give your C9 Christmas light strings an extra layer of weather protection with our professional-grade rubber O-Rings. Specially designed for green E17/C9 base socket wire, these Gaskets create a tight seal between the bulb and socket—keeping out moisture, reducing corrosion, and extending the life of your lights.

Installation is simple: just slide the O-Ring over the bulb base before screwing it into the socket.
