The 3" FIG 1502 Flowline Cross is a high-capacity, 4-way iron fitting designed to serve as a central hub for routing, splitting, and managing high-volume fluid streams in complex oilfield manifold systems. This specific configuration features three Male (Wing Nut) ends and one Female (Threaded) end. The M x M x M x F setup offers rig-up crews exceptional flexibility when tying multiple 3-inch high-pressure flowlines together, making it an indispensable component for heavy-duty choke manifolds, high-rate pump discharge lines, and frac iron spreads.
A significant operational advantage of this cross is the integrated 1/2" NPT Tap machined directly into the heavy-duty forged body. This dedicated port allows field technicians to install critical instrumentation—such as pressure gauges, temperature thermowells, transducer sensors, or chemical injection bleed-off valves—directly at the fluid intersection. By eliminating the need to rig up separate 3-inch gauge spool pieces, this cross drastically reduces the overall footprint and weight of the manifold while eliminating potential leak points on the well pad.
Manufactured for Standard Service, this heavy-duty cross retains the full 15,000 PSI Cold Working Pressure (CWP) rating characteristic of FIG 1502 iron. Forged from premium high-strength alloy steel, it is engineered to withstand the extreme internal scouring of high-velocity frac sand, heavy cement slurries, and massive fluid transfer volumes without compromising structural integrity.
Features & Benefits
-
Integrated 1/2" NPT Tap: Precision-machined port for the direct, leak-free installation of pressure gauges, transducers, or bleed valves, streamlining data acquisition and saving space.
-
15,000 PSI Standard Service: Rated for a massive 15,000 PSI Cold Working Pressure, making it the ideal junction for high-pressure fracturing, cementing, and high-rate flowback operations.
-
High-Volume 3" Capacity: The large 3-inch internal bore handles massive volumes of frac fluid and produced gas, significantly reducing restrictive pressure bottlenecks.
-
M x M x M x F Configuration: The combination of 3 Male (Wing) and 1 Female (Thread) ends provides versatile, hammer-union integration into complex iron networks.
-
Forged Steel Durability: Manufactured from high-strength alloy steel to endure extreme mechanical stress, pressure pulsations, and severe abrasive wear from drill-out debris.

Applications
This 3-inch 1502 cross is universally deployed in high-volume, standard high-pressure applications, including hydraulic fracturing manifolds, heavy-duty cementing heads, well testing, and primary pump discharge lines. The built-in 1/2" NPT tap makes it the preferred junction fitting for operators needing real-time pressure monitoring exactly where multiple fluid streams intersect.
Quality Assurance
Manufactured in accordance with strict API 6A and industry standards for high-pressure oilfield equipment. The raw steel forgings undergo rigorous non-destructive testing (NDT), including ultrasonic (UT) and magnetic particle (MPI) inspections, to ensure the absence of metallurgical defects. The final machined cross is hydrostatically pressure tested up to 22,500 PSI prior to field deployment.
