STZ Industries 4 in. MIP x 2 in. FIP Galvanized Malleable Iron Hex Bushing is a purpose-built connector designed to reliably step down pipe size while withstanding demanding plumbing environments. Built from durable malleable iron and finished in galvanized coating, this hex bushing delivers steady performance in wet, pressurized systems with a focus on long-term corrosion resistance and convenient installation.
Key advantages that matter in real-world projects
-
Clear size transition — converts a 4 in. male iron pipe (MIP) thread to a 2 in. female iron pipe (FIP) thread in a single, compact component, simplifying layout in tight or awkward spaces.
-
Hex head design for easy wrench access and a secure grip, especially when working with larger diameter threads where space is limited.
-
Galvanized malleable iron construction delivers toughness under pressure while resisting corrosion in moist environments, making it suitable for potable water and irrigation systems.
-
Lead-free construction aligns with safety standards for potable water installations, reducing concerns about trace contaminants.
-
Pressure and temperature tolerance rated up to 300 psi and up to 150 °F, providing reliable performance across common residential and light commercial applications.
-
Reliable, bagged packaging helps keep fittings organized and protected during storage and transit.

Installation notes and best practices
- Ensure threads are clean and free of debris before installation.
- Use appropriate thread sealant compatible with galvanized iron threads for a watertight seal.
- Install with the hex head accessible for future maintenance and to prevent over-tightening that could gall or damage threads.
- Verify system pressure and temperature are within the 300 psi / 150 °F ratings to maintain a secure, leak-free connection.
