1 inch Stainless Steel 90 Degree Elbow Female x Female

1 inch Stainless Steel 90° Elbow – Threaded FPT x FPT

The 1 inch Stainless Steel 90-Degree Elbow is a precision-machined fitting designed for directional changes in piping systems where corrosion resistance and structural strength are essential. With its threaded female-to-female configuration, this elbow ensures a reliable connection for Schedule 40 or Schedule 80 piping used in water, air, steam, and non-corrosive fluid systems.

Manufactured from Type 304 or 316 stainless steel, this elbow is built to maintain integrity in environments that demand high mechanical strength and resistance to rust, scale, and thermal cycling. It's suitable for indoor or outdoor use in potable water lines, hydronic heating systems, compressed air lines, and process piping.

Product Highlights

• ✅ Material: Cast or forged 304/316 stainless steel – corrosion-resistant and non-reactive
• ✅ Connection Type: Female National Pipe Thread (NPT) x Female NPT – conforms to ANSI B1.20.1
• ✅ Angle: 90 degrees – ideal for changing pipe direction in confined spaces
• ✅ Wall Thickness: Rated for full-pressure piping systems depending on schedule and material grade
• ✅ Compliance: NSF 61/372 certified (for potable water), ASME B16.3 and B16.11 standards

Installation Considerations

This fitting is designed for use in systems requiring durable, leak-resistant joints. For best results:

• Use PTFE thread seal tape or compatible pipe dope to ensure a gas- or water-tight seal.
• Hand-tighten, then wrench-tighten an additional 1–2 turns to avoid over-torquing stainless threads.
• Inspect threads and mating pipe ends for damage prior to installation.

Typical Applications

• Potable water distribution (hot and cold)
• Closed-loop heating systems
• Compressed air and inert gas lines
• Sanitary and food-grade installations (316 SS preferred)
• Low-pressure steam and condensate return

Performance and Service Life

Stainless steel elbows offer superior longevity in high-humidity, corrosive, or fluctuating temperature conditions. When installed correctly, they can last decades without degrading, unlike galvanized or plastic alternatives in aggressive service environments.

With its reliable NPT threading, corrosion-resistant alloy, and full-pressure capability, the 1 inch Stainless Steel 90° Elbow is a staple in professional-grade mechanical systems. Whether used in a mechanical room, industrial process line, or behind a wall, it ensures performance you can build on.
