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

The Crossover Adapter, 4" FIG 1002 Female (Thread) x 4" FIG 1502 Male (Wing), is a high-capacity, heavy-duty forged steel flowline component designed to safely connect hammer unions of the same large-bore pipe size but different pressure ratings and figure profiles. This crucial adapter allows field operators to seamlessly transition from 4-inch 10,000 PSI (FIG 1002) piping systems to 4-inch 15,000 PSI (FIG 1502) flowline iron without restricting the massive internal flow path or compromising structural integrity.

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 system standards. This adapter eliminates the need for stacking multiple crossover subs, effectively reducing the overall footprint, minimizing potential leak paths, and ensuring a streamlined, high-capacity flow rate with zero bottlenecking. The 4" FIG 1002 end features a precision-machined female thread connection, while the 4" FIG 1502 end includes a male wing configuration complete with a heavy-duty wingnut for fast, hammer-up installation.

Note: While the 4" 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

• Same-Bore Transition: Safely connects 4-inch 10K iron to 4-inch 15K iron, maintaining a massive, uninterrupted flow path for high-volume custom operations.

• 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 4" 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 4-inch-to-4-inch crossover adapter is widely used in high-capacity, high-pressure surface operations where transitioning between different pressure classes of the same diameter is required. Typical applications include massive frac iron rig-ups, high-yield well testing packages, large-bore cementing lines, pump discharge manifolds, and general flowback operations where 4" 10K lines must interface safely with 4" 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.
