1 inch Brass 90 Degree Street Elbow Female x Male

1 inch Brass 90° Street Elbow – Male x Female Threaded Fitting

The 1 inch brass street elbow provides a 90-degree change of direction in a piping system while transitioning from a male to a female threaded connection. Commonly used in water, oil, air, or gas systems, this fitting is engineered for use in high-pressure or high-temperature environments where corrosion resistance and mechanical strength are required.

Specifications and Material Properties

• ✅ Material: Forged brass – known for strength, machinability, and corrosion resistance.
• ✅ Connection: 1 inch Male NPT x 1 inch Female NPT – tapered pipe threads conform to ANSI/ASME B1.20.1.
• ✅ Configuration: 90-degree street elbow for use in directional transitions with one end directly threaded into a fitting.
• ✅ Temperature Rating: Up to 400°F (204°C) depending on application and sealants used.
• ✅ Pressure Rating: Typically rated for 1200 psi (liquid), 150 psi (steam) – varies by installation parameters.

Performance Characteristics

• ✅ Compact Design: Street elbow configuration saves space by eliminating the need for a separate nipple.
• ✅ Mechanical Stability: Maintains thread integrity under system vibration or thermal expansion.
• ✅ Corrosion Resistance: Suitable for potable water, air, oil, fuel, and other non-aggressive media.

Installation Guidelines

Install using standard pipe wrenches with care not to overtighten and risk thread distortion. Pipe dope or PTFE tape is recommended on male threads to improve sealing performance. Ensure proper thread engagement and alignment when installed in confined areas.

Common Applications

This fitting is widely used in residential and commercial mechanical systems including domestic water supply, hydronic heating systems, compressed air networks, and LP/natural gas piping (if brass is approved for the fuel gas code in the local jurisdiction).

Material Note

Brass is a preferred alloy in plumbing for its balance of corrosion resistance, thermal stability, and long-term mechanical durability. Lead-free options are available to meet potable water requirements under NSF/ANSI 61-G and federal SDWA standards.

The 1 inch brass 90-degree street elbow offers a compact, high-integrity solution for directional flow changes and is an essential component for precision installations requiring threaded metal-to-metal sealing. Suitable for new construction or retrofit projects.
