STZ Industries 1-1/2 in FIP x 3/4 in FIP Galvanized Malleable Iron Reducing Coupling is a rugged, lead-free fitting engineered to securely bridge a larger and a smaller pipe run with dependable, leak‑free performance. Its dual FIP (Female Iron Pipe) ends let you connect two threaded pipes without welding, making it a practical choice for repairs, retrofits, and new installations.
Built from durable malleable iron and finished with galvanization, this reducing coupling stands up to moisture, corrosion, and everyday use in potable-water and light commercial applications. It’s designed to handle demanding service while preserving a reliable seal over time.
Key advantages
-
Lead-free construction suitable for potable water and family-friendly installations.
-
Two FIP ends on a single fitting: 1-1/2" FIP on one side and 3/4" FIP on the other for effortless size reduction.
-
Galvanized finish provides corrosion resistance in damp or outdoor environments.
-
Malleable iron body offers durability and a robust, long‑lasting connection.
-
Pressure and temperature rating supports reliable performance up to 300 (max) and up to 150 (max), enabling many standard domestic and light commercial applications.
-
Bagged packaging keeps the fitting clean and protected until installation.
Ideal uses and scenarios
- Repairs or retrofits in potable water lines where a 1-1/2" line must feed a smaller 3/4" branch or appliance.
- Repurposing or extending existing galvanized iron piping in residential, commercial, and light industrial settings.
- Projects where non-welded, threaded connections are preferred for faster installation and easier future disassembly.
