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

The Crossover Adapter, 4" FIG 1002 Male (Wing) x 4" FIG 1502 Female (Thread) with a 7-inch length, is a high-capacity, heavy-duty forged steel flowline component designed to safely connect hammer unions of the same large-bore pipe diameter but different pressure ratings and figure profiles. This crucial adapter allows field operators to transition directly from 4-inch 10,000 PSI (FIG 1002) piping lines to 4-inch 15,000 PSI (FIG 1502) flowline iron without restricting the massive internal flow path or compromising structural integrity.

In high-volume oilfield operations such as massive fracturing jobs, heavy cementing, and large-scale well testing, surface piping layouts frequently require mating equipment from different system standards while bridging precise distance gaps. This crossover features an extended 7-inch overall length, providing essential clearance, reach, and alignment flexibility for custom flowline layouts. It eliminates the need to stack multiple fittings or use short pup joints, significantly 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 male wing configuration complete with a massive, heavy-duty wingnut for fast, hammer-up installation, while the 4" FIG 1502 end includes a precision-machined female thread (sub) connection.

Note: While the 4" FIG 1502 end 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 pressure crossover and a short spacer to accommodate tight or rigid manifold layouts.

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

• Reduced Leak Paths: Single-piece forged construction replaces stacked combinations or short pup joint configurations, drastically reducing potential failure points and lowering operational risk.

• 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 1002 male end includes a heavy-duty wingnut, allowing for rapid, secure makeup and breakout using standard rig hammers.

Specifications & Technical Details

Applications

This 7-inch, 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 and specific gap lengths 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 equipment must safely interface with 4" 15K iron.

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.
