Crossover Adapter – 4" FIG 1502 Male (Wing) x 2" FIG 1502 Female (Thread) | 8" Length

The Crossover Adapter, 4" FIG 1502 Male (Wing) x 2" FIG 1502 Female (Thread) with an extended 8-inch length, is an ultra-heavy-duty, forged steel flowline component engineered to safely handle extreme step-down sizing transitions while precisely bridging a specific spatial gap. This crucial adapter allows field operators to seamlessly transition from massive 4-inch large-bore FIG 1502 flowline headers down to standard 2-inch FIG 1502 equipment without compromising structural integrity or fluid containment in 15,000 PSI systems.

Featuring an extended 8-inch overall length, this component acts simultaneously as a large-bore size-reduction swage and a rigid spacer pup joint. In demanding high-volume operations like hydraulic fracturing, surface layouts frequently require adapting massive 4-inch manifold headers down to 2-inch treatment lines across tight, specific, or rigid physical spans. By bridging this exact 8-inch gap and dropping the line size with a single, integral fitting, this adapter completely eliminates the hazardous need for stacking multiple forged swages and temporary pipe segments. This significantly reduces the overall rig-up footprint, minimizes potential leak paths, and ensures a safer, more streamlined fluid velocity transition.

The 4" FIG 1502 end features a standard heavy-duty male wing configuration complete with a wingnut for fast, hammer-up installation into 4-inch high-capacity equipment. The 2" FIG 1502 end provides a precision-machined female thread (sub) connection designed to safely seat a standard 2-inch male wing profile.

Features & Benefits

• Extended 8-Inch Length: Provides essential reach and alignment clearance, functioning as both a severe size-reduction swage and a short spacer to accommodate complex, rigid large-bore manifold layouts requiring an exact 8-inch bridge.

• Extreme Step-Down Transition: Safely drops pipe diameter from a high-capacity 4-inch large-bore main line down to a standard 2-inch distribution line, providing critical rig-up flexibility.

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

• Reduced Leak Paths: Single-piece integral forged construction replaces hazardous "stacked" combinations of pup joints and swages, drastically reducing potential failure points.

• Fast Field Installation: The 4-inch FIG 1502 male end includes a heavy-duty wingnut, allowing for rapid, secure makeup and breakout using standard rig hammers.

Specifications & Technical Details

Applications

This extended 8-inch Male x Female step-down crossover adapter is widely used in high-pressure surface operations where transitioning from 4-inch main headers to 2-inch lines is required across a specific physical span. Typical applications include massive frac manifold connections, large-bore well testing packages, high-pressure cementing lines, pump discharge manifolds, and general 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.
