Dielectric coupling FF 1 De Dietrich 7660212

The dielectric coupling FF 1 is a fitting used to connect dissimilar metal pipes in heating systems, preventing galvanic corrosion. This coupling features female threads on both ends (FF) and a 1-inch size, making it suitable for boiler and burner installations. As a boiler spare part, it helps maintain system integrity by electrically isolating different metals. When replacing couplings, ensure proper thread type and size to avoid leaks and ensure long-term reliability.
