FIP Galvanized Malleable Iron Coupling is engineered for durable, reliable connections in metal piping systems. With two female iron pipe thread (FIP) ends, this coupling provides a secure, straightforward solution for joining 4-inch pipe segments. The galvanized finish adds exceptional resistance to corrosion, making it suitable for water supply, outdoor installations, and other demanding environments. And with lead-free construction, it aligns with modern safety standards without compromising performance.\u003c\/p\u003e \u003ch2\u003eKey specifications\u003c\/h2\u003e\n\u003cul\u003e \u003cli\u003e\n\u003cstrong\u003eEnd 1 diameter\/type:\u003c\/strong\u003e 4 in.
