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

The Crossover Adapter, 4" FIG 1502 Female (Thread) x 4" FIG 1502 Female (Thread), is an ultra-heavy-duty, forged steel flowline component engineered to securely connect two massive male (wing) hammer union ends within an extreme-volume, 15,000 PSI high-pressure piping system. This integral large-bore adapter provides field operators with a reliable, high-strength solution for maintaining a full 15,000 PSI cold working pressure (15K CWP) flowline without restricting massive fluid flow profiles or sacrificing structural integrity.

A defining feature of this specific crossover is its Female x Female (Thread x Thread) configuration. Both ends of the adapter are precision-machined with female thread (sub) connections, making it an indispensable solution for directly joining two 4-inch male (wing) manifold components together. By bridging these enormous male connections directly, this adapter eliminates the need to fabricate complex workarounds, utilize multiple spacer pup joints, or stack various adapters. This single-piece construction significantly reduces the overall rig-up footprint, minimizes potential leak paths, and limits hazardous exposure points across high-vibration, high-volume systems.

Because both ends utilize the robust, large-bore 4-inch FIG 1502 profile, the entire crossover assembly safely maintains an uninterrupted fluid path to manage extreme-velocity fluids and abrasive slurries with absolute security.

Features & Benefits

• Female x Female Configuration: Precision-machined threads on both ends allow for a direct, streamlined connection between two 4-inch male (wing) hammer unions in complex, large-bore manifolds.

• 15K Extreme-Volume Capacity: Maintains an uninterrupted 4-inch internal flow path rated for a full 15,000 PSI cold working pressure, ideal for extreme high-yield oilfield environments.

• Reduced Leak Paths: Single-piece integral forged construction replaces hazardous "stacked" adapter 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.

• Reliable Sealing: Precision-machined seating surfaces ensure that compatible elastomeric seals seat perfectly for a bubble-tight, leak-free connection under intense pressure.

Specifications & Technical Details

Applications

This Female x Female large-bore crossover adapter is a critical asset for high-pressure surface operations where two massive 4-inch male union components must be securely joined. Typical applications include large-scale frac manifold headers, missile configurations, massive high-rate well testing packages, cementing mainlines, pump discharge manifolds, and general extreme-volume flowback operations requiring secure 15,000 PSI connections.
