Crossover Adapter – 4" FIG 1002 Female (Thread) x 3" FIG 1502 Male (Wing)

The Crossover Adapter, 4" FIG 1002 Female (Thread) x 3" FIG 1502 Male (Wing), is a high-capacity, heavy-duty forged steel flowline component designed to safely and securely connect dissimilar hammer union sizes and pressure ratings. This crucial adapter allows field operators to seamlessly transition from large-bore 4-inch 10,000 PSI (FIG 1002) piping systems down to 3-inch 15,000 PSI (FIG 1502) flowline iron without compromising structural integrity or sealing performance.

In complex, high-volume oilfield operations such as massive fracturing jobs, heavy cementing, and large-scale well testing, rig-ups often require mating equipment from different systems. This crossover eliminates the need for stacking multiple fittings to bridge size and pressure gaps, reducing the overall footprint, minimizing potential leak paths, and ensuring a streamlined, high-capacity flow rate. The 4" FIG 1002 end features a precision-machined female thread connection, while the 3" FIG 1502 end includes a male wing configuration complete with a heavy-duty wingnut for fast, hammer-up installation.

Note: While the 3" FIG 1502 connection is nominally rated for 15,000 PSI, the overall working pressure of this crossover assembly is strictly limited by the 4" FIG 1002 connection, resulting in a maximum system pressure rating of 10,000 PSI (10K CWP).

Features & Benefits

• Seamless Large-Bore Transition: Safely connects 4-inch 10K iron to 3-inch 15K iron, providing essential flexibility for custom large-volume manifold and flowline rig-ups.

• Reduced Leak Paths: Acts as a single, integral adapter, eliminating the need to stack multiple fittings and thereby drastically reducing potential failure points.

• Heavy-Duty Forged Construction: Manufactured from high-strength alloy steel to withstand severe shock loads, extreme vibration, and massive volumes of abrasive fluid flow.

• Fast Installation: The 3" FIG 1502 male end includes a heavy-duty wingnut, allowing for rapid, secure makeup and breakout using standard rig hammers.

• Reliable Sealing: Precision-machined seating surfaces and compatible elastomeric seals ensure a bubble-tight, leak-free connection under high pressure.

Specifications & Technical Details

Applications

This large-bore crossover adapter is widely used in high-capacity, high-pressure surface operations where transitioning between different pipe diameters and pressure classes is required. Typical applications include heavy frac iron rig-ups, high-yield well testing packages, large-bore cementing lines, choke and kill manifolds, and general flowback operations where 4" 10K lines must feed into 3" 15K equipment.

Quality Assurance

All our crossover adapters are manufactured from premium forged alloy steel and subjected to strict quality control processes. Each fitting undergoes rigorous dimensional inspection and hydrostatic pressure testing prior to shipment to ensure absolute safety, shell integrity, and seal performance under maximum working loads. Full material traceability is available to guarantee compliance with API guidelines.
