A Latrolet (also known as a Lateral Outlet) is a specialized branch connection fitting used to create a 45° lateral branch from a main run pipe. This design is ideal for applications requiring an angled take-off for specific piping layouts or to improve flow dynamics by reducing turbulence compared to a standard 90° connection. Manufactured through a forging process, Latrolets provide integral reinforcement and exceptional mechanical strength. They are available with Butt Weld (BW), Socket Weld (SW), or Threaded (NPT/BSP) outlet connections, making them highly versatile. Commonly made from carbon steel, stainless steel, and alloy steels, they are used in high-pressure, high-temperature services within the oil & gas, petrochemical, and power generation industries.

| Latrolet Design Features |
45° Branch: Creates a smooth, angled branch, reducing turbulence. Forged Strength: Provides integral reinforcement for the branch connection. Versatile Outlets: Available in BW, SW, and Threaded ends. Run Pipe Fit-Up: Contoured base for a clean, secure weld to the run pipe. Standard Compliance: Manufactured per MSS-SP-97. |
Creates a high-strength, integrally reinforced 45° branch off a main run pipe, ideal for angled piping runs and specialized flow applications.
Manufactured using advanced forging techniques to ensure high mechanical strength and reliability in high-pressure and high-stress applications.
Available in Butt Weld (BW), Socket Weld (SW), and Threaded (NPT/BSP) outlet types to match various branch piping and instrumentation requirements.
Designed and manufactured in full accordance with MSS-SP-97 and ASTM material standards for guaranteed quality and global compatibility.
The 45° angle provides a smoother flow transition and reduces turbulence and pressure drop compared to a standard 90° tee, improving system efficiency.
Available in a full range of materials including carbon steel, stainless steel, and nickel alloys to ensure long-term performance in corrosive environments.
