1-1/4 inch Stainless Steel Tee Female x Female x Female

1-1/4 Inch Stainless Steel Threaded Tee – FPT x FPT x FPT

This 1-1/4 inch stainless steel tee fitting provides a durable solution for branch connections in threaded pipe systems. Manufactured for compatibility with ANSI standard threaded pipe, it is commonly used in fluid transfer, air, and non-potable water systems in both commercial and industrial environments.

Product Specifications

• Material: 304 stainless steel, cast or forged construction
• Size: 1-1/4 inch nominal
• Connection: NPT female x female x female
• Pressure Rating: Up to 150 psi (depending on system configuration)
• Compliance: Conforms to ASTM A351 (or A182 for forged), ANSI/ASME B16.3 for dimensions and threading

Features and Applications

• Corrosion Resistance: Suitable for applications where rust or chemical exposure is a concern
• Mechanical Strength: Capable of handling temperature fluctuations and mechanical vibration in industrial systems
• Precision Threads: Threaded to national standards to ensure tight fit and reliable sealing when used with appropriate sealing compounds
• Use Cases: Water distribution lines, compressed air systems, low-pressure steam, and chemical transport (non-hazardous)

Installation Guidelines

Use Teflon tape or pipe joint compound to ensure leak-free performance at threaded joints. Avoid over-torquing during installation to prevent thread damage or cracking. Always verify compatibility with piping materials and ensure pressure ratings align with system specifications. Not recommended for potable water unless 316 stainless or NSF-certified 304 is confirmed.

Common Environments

Frequently used in manufacturing facilities, mechanical rooms, fire protection loops, and service branches requiring a corrosion-resistant and mechanically robust tee fitting. Also applicable in process piping systems where threaded stainless connections are permitted.

Technical Note

Threaded tees are advantageous in retrofit applications and repair work due to their ease of installation. However, for high-cycle vibration-prone applications, welded or flanged assemblies may be preferred for added longevity and integrity.

The 1-1/4 inch stainless steel FPT tee provides a long-lasting, corrosion-resistant solution for piping transitions requiring a branch connection. Its mechanical properties and compliance with standard specifications make it a dependable component in demanding plumbing and mechanical systems.
