STZ Industries 4 in. FIP x 4 in. MIP 90 Degree Street Elbow is built to power tight, reliable piping runs with confidence. Crafted from durable malleable iron and finished in galvanization, this lead-free elbow stands up to the demands of potable water and light-industrial piping while easing installation in cramped spaces.
-
FIP x MIP with a true 90° street design: One end is Female Iron Pipe (FIP) and the other is Male Iron Pipe (MIP), delivering a precise 90° turn. The street configuration lets you connect from the threaded line more easily, reducing installation time and alignment hassles in tight enclosures.
-
Lead-free for potable applications: The average lead content is eliminated, making this fitting suitable for potable water systems and improving safety for everyday use.
-
Galvanized malleable iron for lasting durability: The galvanizing provides corrosion resistance in exposed or damp environments, while the malleable iron construction handles vibration and pressure spikes common in commercial and residential installs.
-
Solid pressure and temperature ratings: Rated to 300 psi and up to 150°F, this elbow handles typical water-service conditions and many light-industrial piping scenarios without compromising integrity.
-
Large 4 inch size with standard threading: Standard pipe threads ensure compatibility with compatible 4 in. FIP and MIP piping in a wide range of systems, from distribution mains to retrofit projects.
-
Bagged packaging for convenient handling: Sold bagged to protect threads during storage and shipping, helping prevent damage prior to installation.
Why this elbow stands out in a crowded market is its combination of lead-free assurance, robust galvanized malleable-iron construction, and a practical street elbow design that simplifies alignment in confined spaces. It’s a reliable choice for plumbers, facilities managers, and DIY installers tackling potable water lines, sprinkler mains, and other threaded piping runs where space is at a premium.
Ideal use cases: Installing or repairing 4 inch water supply lines in basements, crawl spaces, or utility rooms; upgrading outdoor sprinkler mains where corrosion resistance matters; retrofitting existing galvanized systems in commercial buildings; and any project requiring a trustworthy FIP x MIP 90° turn without bulky fittings.
Installation tips: Apply plumber’s tape or thread sealant compatible with potable water on each threaded connection. Hand-tighten first, then snug with a wrench—avoid over-tightening to preserve thread integrity. Check all joints for leaks after pressurizing the system and before shifting into full operation.
