Crossover Adapter – 4" FIG 1002 Male (Wing) x 2" FIG 1502 Female (Thread)

The Crossover Adapter, 4" FIG 1002 Male (Wing) x 2" FIG 1502 Female (Thread), is a heavy-duty, forged steel flowline component engineered to safely and securely bridge the gap between dissimilar hammer union sizes and pressure ratings. This essential adapter allows field operators to seamlessly step down from large-bore 4-inch 10,000 PSI (FIG 1002) piping systems to standard 2-inch 15,000 PSI (FIG 1502) flowline iron without compromising structural integrity or sealing performance.

In complex oilfield operations such as fracturing, cementing, and well testing, rig-ups often require transitioning from high-volume trunk lines to smaller distribution manifolds. This crossover eliminates the need for stacking multiple swages and fittings to bridge the size and pressure gap, significantly reducing the overall footprint, minimizing potential leak paths, and ensuring a safer rig-up.

The 4" FIG 1002 end features a male wing configuration complete with a massive, heavy-duty wingnut for fast, hammer-up installation, while the 2" FIG 1502 end includes a precision-machined female thread (sub) connection.

Note: While the 2" 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

• Large-to-Small Bore Transition: Safely steps down from large-bore 4-inch 10K iron to standard 2-inch 15K iron, providing essential flexibility for custom manifold and flowline distributions.

• Reduced Leak Paths: Acts as a single, integral step-down adapter, eliminating the need to stack multiple crossover 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 abrasive fluid flow.

• Fast Installation: The 4" FIG 1002 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 step-down crossover adapter is widely used in high-pressure surface operations where transitioning from high-volume large-bore lines to smaller distribution lines is required. Typical applications include stepping down from 4" frac trunk lines to 2" missile manifolds, well testing packages, cementing lines, and general flowback operations where 4" 10K equipment must safely feed into 2" 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.
