Our Galvanized Malleable Iron Elbow 90 is a high-performance piping component engineered for precision flow direction changes in demanding industrial environments. Manufactured from premium black heart malleable iron and treated with a robust hot-dipped galvanized finish, these elbows provide exceptional resistance to rust, oxidation, and corrosion when exposed to water, air, and steam applications.
Designed for maximum reliability, our 90-degree elbows feature National Pipe Taper (NPT) threads, ensuring a tighter, leak-proof seal compared to straight threads. Whether you are managing oil, gas, or pneumatic systems, these fittings offer the ideal balance of tensile strength and durability, adhering to strict international standards including ISO, ANSI, and DIN to guarantee seamless integration into your existing infrastructure.

Frequently Asked Questions
Malleable iron undergoes a heat treatment process (annealing) that removes brittleness, providing much higher tensile strength and impact resistance compared to standard cast iron.
National Pipe Taper (NPT) threads are tapered, meaning they tighten as they are screwed together, creating a more secure, leak-proof seal essential for gas and liquid transport.
Yes, the hot-dipped galvanized finish is specifically designed to resist rust and corrosion in water, air, and steam environments, making it ideal for outdoor or industrial installations.
Our fittings have a standard working pressure of 1.6MPA (16KG/CM²) and are rigorously tested up to 2.5MPA to ensure safety and reliability.
