1-1/4 inch Stainless Steel 90 Degree Elbow Female x Female

1-1/4 inch Stainless Steel 90° Elbow – Threaded Fitting for Directional Flow in Piping Systems

The 1-1/4 inch stainless steel 90-degree elbow is a threaded pipe fitting designed to change flow direction by 90 degrees within mechanical, water, or process piping systems. Made from corrosion-resistant stainless steel, this fitting is engineered for high durability in environments subject to pressure, temperature variation, or chemical exposure.

It features female National Pipe Thread (NPT) ends and is suitable for Schedule 40 stainless steel piping. The fitting is commonly used in applications requiring precise directional changes in systems where corrosion resistance and pressure retention are critical.

Technical Specifications

• Material: 304 or 316 stainless steel (verify per project spec)
• Size: 1-1/4 inch nominal pipe size
• Connection Type: Female NPT x Female NPT
• Wall Type: Compatible with Schedule 40 stainless steel pipe
• Standards: Manufactured to ASME B16.11 or MSS-SP-114, depending on grade

Functional Attributes

• ✅ Corrosion-Resistant Alloy Stainless steel construction resists degradation from moisture, air, and a wide range of chemicals
• ✅ Threaded Connection Female NPT threads support easy disassembly and rework during system modification or maintenance
• ✅ Temperature and Pressure Ratings Suitable for high-temperature and moderate-pressure applications, depending on system design
• ✅ Durable Design Maintains integrity under mechanical stress and fluid dynamics

Installation Notes

Threaded stainless steel fittings should be installed using approved thread sealants compatible with the application (e.g., PTFE tape or pipe dope rated for stainless steel). Over-tightening should be avoided to reduce the risk of galling, a common concern with stainless steel threads. For critical systems, hydrostatic or pneumatic testing is recommended after assembly.

Typical Use Cases

The 1-1/4 inch stainless steel 90-degree elbow is used in:

• Process piping in chemical and food-grade facilities
• Potable and non-potable water supply systems
• Fire protection, HVAC, and mechanical equipment tie-ins
• Corrosion-prone or outdoor fluid systems

Material Insight

Stainless steel pipe fittings offer excellent mechanical strength and resistance to scaling and rusting. Depending on the alloy grade selected, these fittings are suitable for contact with potable water, steam, and various process fluids. They are also fully recyclable, aligning with sustainable construction practices.

The 1-1/4 inch stainless steel 90° elbow provides a robust, code-compliant solution for turning pipe runs in demanding mechanical systems. Its corrosion-resistant build and reliable threading make it a preferred choice in industrial, commercial, and utility applications where performance and durability are required.
