The Galvanized Malleable Iron 90-Degree Elbow is a professional-grade piping component engineered for precise right-angle directional changes in fluid transport systems. Manufactured from high-strength malleable cast iron and enhanced with a high-temperature hot-dip galvanizing process, it creates a dense zinc-iron alloy layer that ensures exceptional structural integrity and superior protection against oxidation.
Designed for versatility and longevity, these elbows are the ideal choice for challenging industrial environments, including humid outdoor installations and low-pressure fluid systems. By combining mechanical toughness with advanced corrosion resistance, our 90-degree elbows provide a reliable, leak-proof foundation for critical infrastructure, ensuring stable system operation and reduced maintenance costs over time.

| Feature | Standard Cast Iron | Galvanized Malleable Iron |
|---|---|---|
| Corrosion Life | Short-term (prone to rust) | Long-term (High resistance) |
| Impact Strength | Brittle (Risk of cracking) | High (Shock absorbent) |
| Maintenance Frequency | High / Frequent repairs | Low / Durable performance |
| Installation Speed | Moderate | Fast (Precision threads) |
| Overall ROI | Lower (High replacement cost) | Higher (Lower life-cycle cost) |
Malleable iron is heat-treated to remove carbon stresses, making it significantly tougher and less brittle than standard cast iron, providing better resistance to shock and pressure.
It creates a metallurgical bond between the zinc and the iron, forming multiple alloy layers that act as a sacrificial barrier, preventing rust even in humid or outdoor environments.
Our fittings strictly adhere to standard tapered pipe threads (Rc/R), ensuring seamless compatibility with standard piping systems globally.
These are specifically designed for general industrial low-pressure fluid transport systems. For high-pressure steam, please consult our technical team for specialized high-pressure options.
We provide a comprehensive range of nominal diameters from DN15 (1/2") up to DN150 (6") to meet various project requirements.
While our threads are precision-machined, we recommend using PTFE tape or a professional-grade pipe sealant during installation to achieve a completely leak-proof connection.
