4" ANSI 150# x 3" Fig 206 Male Wing Flange Adapter – Oil & Gas Flowline Fitting

The 4" ANSI 150# x 3" Fig 206 Male Wing Flange Adapter is a dependable, low-pressure crossover component designed to seamlessly connect standard facility piping with temporary fluid flowlines. Engineered for efficient fluid transfer in upstream, midstream, and industrial operations, this size-reducing adapter bridges a permanent 4-inch ANSI Class 150 flanged connection down to a standard 3-inch Figure 206 hammer union interface. The integrated 3-inch male wing nut enables fast, tool-free makeup in the field, critically reducing rig-up times for temporary routing or transfer systems.

Manufactured from high-strength forged steel, this crossover adapter is built to endure the rigors of field handling and consistent fluid transfer. The Figure 206 standard incorporates a secondary O-ring seal embedded in the male sub (this adapter's union end), which provides enhanced, leak-free performance and superior sealing even in less-than-ideal alignment conditions. This makes it exceptionally well-suited for general fluid transfer, low-pressure water lines, mud mixing systems, and suction headers.

Serving as a critical interface between permanent facility infrastructure and temporary hoses or piping, this male wing flange adapter optimizes layout flexibility while maintaining operational safety. (Note: The maximum working pressure of the assembly is governed by the ANSI Class 150 flange rating).

Features & Benefits

• Rapid Makeup Design: Features an integrated 3" Figure 206 Male Wing Nut for quick, ultra-secure hammer union connections without specialized tools.

• Seamless Size Transition: Efficiently steps down fluid flow from a larger 4-inch ANSI Class 150 facility pipe to a standard 3-inch temporary line.

• Secondary O-Ring Sealing: The Figure 206 male connection utilizes an embedded O-ring for superior, leak-tight sealing in fluid and mud applications.

• Forged Steel Construction: Built to handle industrial fluid transfer, mechanical impacts, and general oilfield handling without compromising structural integrity.

• Versatile Utility: Ideal for mud systems, water transfer, chemical injection lines, and low-pressure facility tie-ins.

• Service Ready: Manufactured to meet rigorous quality, dimensional, and material verification standards for standard industrial service.

Specifications & Technical Details

Applications

This ANSI 150# flange to Figure 206 male wing union adapter is essential for operations requiring a secure, low-pressure, size-reducing transition between permanent facility piping and temporary flowline equipment. Typical applications include midstream facility tie-ins, mud mixing networks, high-volume water transfer, suction lines, and standard industrial pump connections.

Quality Assurance

Each crossover adapter undergoes strict quality inspection protocols, including dimensional checks, precision thread and wing nut gauging, flange facing inspection, and material verification to ensure safe, leak-free, and reliable field performance in everyday transfer applications.
