1/2 inch Black Iron 90 Degree Street Elbow Female x Male

BLK MAL ST90ELL 1/2 inch Street Elbow – Built for Secure Transitions

The BLK MAL ST90ELL 1/2 inch Street Elbow is a 90-degree fitting designed to connect malleable iron pipe runs where space is restricted. With one male and one female threaded end, it eliminates the need for additional couplings, reducing material use and potential leak points. This makes it a preferred component in applications requiring compact directional changes.

Manufactured from black malleable iron in compliance with ASTM A197 standards, this elbow offers mechanical strength and pressure resistance for use in non-potable water, gas, and steam systems. The threads are machined to ANSI/ASME B1.20.1 standards, ensuring compatibility with standard pipe and fittings and reliable, tight connections in both residential and commercial installations.

Key Advantages

• ✅ Space-Saving Design: Street elbow configuration allows for tighter directional changes without a separate nipple
• ✅ Threaded Connections: Features one NPT male and one NPT female end for inline compatibility with black iron pipe systems
• ✅ Pressure Rated: Suitable for low- to medium-pressure systems such as air, gas, and oil distribution lines
• ✅ Material: Black malleable iron castings ensure strength and durability in challenging service environments
• ✅ Corrosion-Resistant Finish: Black oxide coating helps protect the surface during storage and initial installation

Technical Specifications

• Material: Black Malleable Iron (ASTM A197)
• Connection Type: 1/2 inch NPT Male x 1/2 inch NPT Female
• Angle: 90 Degrees
• Standards: ANSI/ASME B16.3, B1.20.1
• Applications: Non-potable water, gas, air, steam systems

Application and Use

These fittings are widely used in heating systems, natural gas lines, compressed air installations, and fire protection piping. They are especially useful in retrofits where space constraints demand compact transitions. For best results, ensure threads are clean and use thread sealant appropriate for the system media.

Field Insight

Street elbows offer efficiency in layout by directly joining a pipe to another fitting without needing extra couplings, which can reduce material cost and minimize potential leak paths in piping configurations.

Engineered for performance and reliability, the BLK MAL ST90ELL 1/2 inch Street Elbow meets the demands of professional-grade plumbing installations. Its durable construction and precision threads make it an essential component in pressure-rated iron pipe systems.
