Crossover Adapter – 4" FIG 1502 Male (Wing) x 3" FIG 1502 Male (Wing)

The Crossover Adapter, 4" FIG 1502 Male (Wing) x 3" FIG 1502 Male (Wing), is an ultra-heavy-duty, forged steel flowline component engineered to safely handle massive step-down sizing transitions within extreme 15,000 PSI high-pressure piping systems. This crucial adapter allows field operators to seamlessly transition from extreme-capacity 4-inch large-bore FIG 1502 flowline headers down to standard 3-inch FIG 1502 equipment without restricting flow profiles or compromising fluid containment.

A distinct defining feature of this specific step-down crossover is its Male x Male (Wing x Wing) configuration. Both ends of the adapter are equipped with standard heavy-duty FIG 1502 wingnuts (one 4-inch, one 3-inch). This makes it an indispensable, highly specific solution for directly joining a massive 4-inch female (thread/sub) manifold connection directly to a 3-inch female (thread/sub) line. By bridging these two differently sized female connections, this integral adapter eliminates the need for stacking multiple forged swages, pup joints, or temporary crossovers. This significantly reduces the overall rig-up footprint, minimizes potential leak paths, and ensures a safer, more streamlined fluid transition during high-velocity operations.

Because both ends utilize the robust FIG 1502 profile, the entire crossover assembly safely maintains a full 15,000 PSI cold working pressure rating across the severe size transition.

Features & Benefits

• Male x Male Configuration: Features heavy-duty wingnuts on both ends, providing a direct, streamlined solution for mating a massive 4-inch female connection to a standard 3-inch female connection in complex rig-ups.

• High-Volume Step-Down Transition: Safely drops pipe diameter from a high-capacity 4-inch large-bore main line down to a 3-inch line, providing critical rig-up flexibility for massive fluid volumes.

• Full 15K CWP Capacity: Maintains an uninterrupted high-pressure rating of 15,000 PSI (15K CWP) across the entire step-down transition, built for extreme oilfield environments.

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

• Fast Field Installation: Dual heavy-duty wingnut ends allow for rapid, secure makeup and breakout on both sides using standard rig hammers.

Specifications & Technical Details

Applications

This Male x Male step-down crossover adapter is widely used in high-pressure surface operations where transitioning from 4-inch main headers to 3-inch distribution lines is required, specifically when two female union components must be directly joined. Typical applications include massive frac manifold connections, large-bore well testing packages, high-pressure cementing lines, pump discharge manifolds, and general extreme-volume flowback operations requiring secure 15,000 PSI step-down connections.

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.
