Crossover Adapter – 4" FIG 206 Male (Wing) x 4" FIG 206 Male (Wing) | Butt Welded, SCH XH

The Crossover Adapter, 4" FIG 206 Male (Wing) x 4" FIG 206 Male (Wing), is a heavy-duty, fabricated flowline component engineered to securely connect two massive female (thread/sub) hammer union ends within a 2,000 PSI low-pressure fluid transfer system. Utilizing a highly durable Butt Welded Schedule XH (Extra Heavy) pipe construction, this large-bore adapter acts as a rigid fluid bridge or spacer, allowing field operators to safely join two 4-inch FIG 206 female connections without restricting massive fluid flow profiles.

In standard surface operations, FIG 206 connections are the industry standard for low-pressure applications, utilizing a secondary O-ring seal to ensure bubble-tight fluid containment. By bridging two differently positioned female connections directly, this integral welded adapter eliminates the need to fabricate temporary, multi-piece threaded workarounds. The Butt Welded SCH XH construction provides superior structural integrity, resisting severe vibration and erosive wear commonly found in abrasive mud and slurry lines.

Both ends of this large-bore adapter feature a standard low-pressure 4-inch male wing configuration complete with a heavy-duty wingnut and the signature FIG 206 O-ring seal for fast, secure installation. The entire welded assembly is continuously rated for a 2,000 PSI cold working pressure (2K CWP).

Features & Benefits

• Butt Welded SCH XH Construction: Fabricated using premium Schedule XH (Extra Heavy) pipe for superior structural integrity, extreme vibration resistance, and longevity in large-volume abrasive fluid transfer.

• Male x Male Configuration: Features standard 206 wingnuts on both ends, providing a direct, streamlined solution for mating two 4-inch female connections in complex large-bore rig-ups.

• O-Ring Sealed Profile: The FIG 206 male ends incorporate primary O-ring seals, ensuring reliable, leak-free fluid containment even in high-volume suction or low-pressure fluid transfer applications.

• 2K Working Capacity: Maintains an uninterrupted pressure rating of 2,000 PSI, ideal for extreme-volume water, mud, and fluid return environments.

• Reduced Leak Paths: Replacing hazardous "stacked" threaded nipples with a single butt-welded assembly drastically reduces potential failure points and lowers operational risk.

Specifications & Technical Details

Applications

This welded 4-inch Male x Male crossover adapter is an essential asset in large-scale surface operations requiring reliable, high-volume low-pressure fluid transfer. Typical applications include massive mud tank suction lines, high-capacity fluid return headers, cement mixing manifolds, water transfer systems, and general large-bore flowline operations where operators must directly connect two 4" 206 female components.

Quality Assurance

All our welded crossover adapters are fabricated by certified welders using premium alloy steel and subjected to strict quality control processes. Each fabricated fitting undergoes rigorous weld inspection and hydrostatic pressure testing prior to shipment to ensure absolute safety, shell integrity, and seal performance under working loads. Full material traceability is available to guarantee compliance with API guidelines.
