Crossover Adapter – 4" FIG 1502 Female (Thread) x 3" FIG 1502 Male (Wing) | 7" Length

The Crossover Adapter, 4" FIG 1502 Female (Thread) x 3" FIG 1502 Male (Wing) with an extended 7-inch length, is an ultra-heavy-duty, forged steel flowline component engineered to safely handle high-capacity step-down sizing transitions while precisely bridging a specific spatial gap. This crucial adapter allows field operators to seamlessly transition from extreme 4-inch large-bore FIG 1502 main lines down to standard 3-inch FIG 1502 equipment without restricting flow profiles or compromising system containment.

Featuring an extended 7-inch overall length, this component acts simultaneously as a large-bore size-reduction swage and a rigid spacer pup joint. In demanding oilfield layouts like hydraulic fracturing manifolds or high-rate well testing rigs, piping setups frequently require dropping down from a 4-inch main header to a 3-inch distribution line across tight or rigid spans. By bridging this size and spatial gap with a single, integral 7-inch fitting, this adapter eliminates the need for stacking multiple forged swages and temporary pipe pieces. This significantly reduces the overall rig-up footprint, minimizes potential leak paths, and ensures a safer, more streamlined fluid velocity transition under an intense 15,000 PSI high-pressure environment.

The 4" FIG 1502 end features a precision-machined female thread (sub) connection designed to safely seat a 4-inch male wing, while the 3" FIG 1502 end is equipped with a standard heavy-duty male wingnut for fast hammer-up integration.

Features & Benefits

• Extended 7-Inch Length: Provides essential reach and alignment clearance, functioning as both a size-reduction swage and a short spacer to accommodate complex, rigid large-bore manifold layouts.

• High-Volume Step-Down Transition: Safely drops pipe diameter from a high-capacity 4-inch large-bore main line down to a standard 3-inch 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 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 3-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 7-inch Female x Male step-down crossover adapter is widely used in high-pressure surface operations where transitioning from 4-inch main headers to 3-inch lines is required across a specific physical span. Typical applications include large-bore frac manifold connections, massive 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.
