Solve tight-pipe routing with confidence using the STZ Industries 3 in. FIP x 3 in. FIP Black Malleable Iron 45 Degree Elbow. Crafted from tough malleable iron and finished in a durable black coating, this elbow delivers reliable, long-lasting performance for potable water, heating, and general piping applications. With full 3-inch female threaded ends on both sides, it installs quickly onto standard 3 in. FIP connections, making it a natural fit for mid- to large-diameter systems.
Key advantages
-
Lead-free composition: Designed for safe potable-water installations, reducing concerns about lead in your plumbing system.
-
Robust 3 in. FIP to 3 in. FIP ends: Simple, secure threaded connections that integrate with standard piping without adapters.
-
45-degree geometry: Smooths the flow path while preserving line pressure, ideal for navigating around obstacles or changing direction with less turbulence than a sharp turn.
-
High-strength malleable iron: Superior impact resistance and durability in commercial and industrial environments compared to lesser alloys.
-
Black finish: Provides a corrosion-resistant exterior suitable for indoor use in moderate environments and adds a clean, professional look to visible plumbing runs.
-
Engineered for demanding conditions: Rated up to 300 psi and 150°F, making it suitable for typical hot-water and light industrial applications.
-
Bagged packaging: Protects the component during storage and transit, simplifying inventory management.
Ideal uses and scenarios
- Connecting large-diameter water lines in residential, commercial, or light industrial systems where a gradual 45° change minimizes stress on joints.
- Retrofits and upgrades in heating systems, where a reliable, lead-free elbow helps maintain flow efficiency and safety.
- Potable-water distribution runs in buildings that require durable, code-compliant fittings with robust thread integrity.
Installation tips
- Prepare threads with appropriate pipe-thread sealant or PTFE tape rated for potable water, applying evenly on male threads before tightening.
- Fully engage thread connections by hand to a snug fit, then use an appropriate wrench to finish tighten. Avoid over-tightening to prevent thread damage.
- Inspect each joint after assembly for leaks and ensure alignment to reduce strain on the elbow and connected piping.
