Crossover Adapter – 4" FIG 1002 Male (Wing) x 3" FIG 1502 Female (Thread) | 7" Length

The Crossover Adapter, 4" FIG 1002 Male (Wing) x 3" FIG 1502 Female (Thread) with a 7-inch length, is a high-capacity, heavy-duty forged steel flowline component engineered to safely connect dissimilar hammer union sizes, figure profiles, 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 oilfield operations such as high-rate fracturing, heavy cementing, and large-scale well testing, rig-ups often require transitioning from high-volume trunk lines to slightly smaller distribution manifolds while bridging precise distance gaps. This crossover features an extended 7-inch overall length, providing essential clearance and reach for custom flowline configurations. It eliminates the need to stack multiple swages, short pup joints, or adapters, significantly reducing the overall footprint, minimizing potential leak paths, and ensuring a safer, more streamlined rig-up.

The 4" FIG 1002 end features a male wing configuration complete with a massive, heavy-duty wingnut for fast, hammer-up field assembly, while the 3" FIG 1502 end includes a precision-machined female thread (sub) connection.

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

• Extended 7-Inch Length: Provides additional reach and alignment clearance, acting as both a step-down crossover and a short spacer to accommodate tight or rigid manifold layouts.

• Large-to-Medium Bore Transition: Safely steps down from large-bore 4-inch 10K iron to 3-inch 15K iron, offering exceptional flexibility for custom manifold and flowline distributions.

• Reduced Leak Paths: Single-piece forged construction replaces hazardous "stacked" adapter configurations, drastically reducing potential failure points and minimizing pressure drops.

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

• Fast Field Installation: The 4" FIG 1002 male end features an integral heavy-duty wingnut, allowing for rapid, secure makeup and breakout using standard rig hammers.

Specifications & Technical Details

Applications

This extended 7-inch step-down crossover adapter is widely used in high-capacity, high-pressure surface operations where transitioning between different pipe diameters, pressure classes, and specific gap lengths is required. Typical applications include stepping down from 4" frac trunk lines to 3" manifolds, high-yield well testing packages, large-bore cementing lines, and general flowback operations where 4" 10K equipment must safely interface with 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.
