2-9/16" 5M x 2-1/16" 5M Double Studded Adapter (DSA) with Studs & Nuts – Oil & Gas Flowline Fitting

The 2-9/16" 5M x 2-1/16" 5M Double Studded Adapter (DSA) is a highly specialized transition component engineered to seamlessly connect API 6A flanged equipment of differing sizes and pressure ratings in high-pressure wellhead and manifold systems. Designed for demanding upstream operations, this compact crossover allows operators to safely adapt a 2-9/16" 5,000 PSI (5M) connection to a 2-1/16" 5,000 PSI (5M) interface without adding significant height or weight to the assembly.

Manufactured from premium AISI 4130 alloy steel with a 75K yield strength, this DSA provides exceptional structural integrity and reliable pressure containment against abrasive drilling fluids, hydrocarbons, and severe field vibrations. To ensure immediate field readiness and minimize rig-up delays, this unit is supplied fully equipped with the correctly sized, high-strength studs and heavy hex nuts required for both studded faces.

Serving as a vital pressure-control link, the Double Studded Adapter optimizes layout flexibility and structural safety across wellhead trees, BOP stacks, and complex manifold configurations.

Features & Benefits

• Seamless Size Transition: Safely and efficiently bridges a 2-9/16" API flanged asset to a 2-1/16" interface, maintaining continuous fluid flow.

• 5,000 PSI Rating (5M): Engineered and tested to safely contain extreme high-pressure upstream environments.

• Premium 4130 75K Steel: Constructed from high-grade AISI 4130 forged alloy steel (75,000 PSI minimum yield strength) for superior durability and impact resistance.

• Compact Studded Design: Minimizes spatial requirements, overall weight, and stack height compared to traditional flanged spools.

• Installation Ready: Comes fully supplied with exact-specification studs and nuts, eliminating the need for separate hardware sourcing and reducing downtime.

• API 6A Compliant: Manufactured to recognized industry standards to ensure universal compatibility and rigorous operational reliability.

Specifications & Technical Details

Applications

This 5M Double Studded Adapter is essential for upstream operations requiring structurally sound and compact transitions between mismatched flanged connections. Typical applications include adapting wellhead tree components, interfacing different sizes of Blowout Preventer (BOP) stacks, choke and kill manifold transitions, well testing setups, and adapting high-pressure valving to existing flowline networks.

Quality Assurance

Each DSA undergoes rigorous quality control protocols, including hydrostatic testing, full dimensional verification, precise ring groove and thread inspection, and complete material traceability (MTRs), ensuring strict compliance with API 6A standards for dependable high-pressure field performance.
