The 4" Figure 206 Male Blind Sub (Wing Half) is a large-bore, medium-pressure closure component designed to securely cap off and isolate female threaded hubs in hammer union systems. Rated for a Cold Working Pressure (CWP) of 2,000 PSI, this fitting is ideal for high-volume water transfer, mud lines, and general utility systems where a dependable, leak-proof seal is required.

Manufactured from high-strength forged steel, this male blind sub features the signature Figure 206 design: an integrated O-ring groove machined into the sealing face. This secondary O-ring seal provides superior leak prevention and bubble-tight performance compared to standard metal-to-metal unions, which is particularly beneficial in large 4-inch lines subject to heavy vibration or slight piping misalignment. Designed to be assembled with a standard 4" Fig 206 wing nut (often utilized with existing wing nuts or sold as a complete assembly), this component provides a safe, blowout-proof termination point for medium-pressure manifolds.

Built to withstand the rigors of heavy field use, the 4" 206 Male Blind Sub ensures robust fluid containment and simplified flowline management in standard-duty oilfield applications.

Features & Benefits

  • 2,000 PSI CWP Rating: Specifically engineered for reliable pressure containment in large-volume utility, mud, and water transfer environments.

  • O-Ring Sealing Technology: Features an integrated O-ring groove for superior leak prevention and bubble-tight sealing under vibration.

  • Forged Steel Construction: Delivers high structural integrity and impact resistance to endure repeated make-and-break cycles in the field.

  • Positive Isolation: Provides a secure and immediate dead-end for 4-inch flowlines and manifold branches.

  • Standard Interchangeability: Fully compatible with all industry-standard 4" Figure 206 female threaded hubs and wing nuts.

  • Rapid Deployment: Allows rig crews to quickly cap off unused lines using standard hammer-up techniques, minimizing downtime.

Applications

This 4" Figure 206 male blind sub is essential for medium-pressure, large-bore operations requiring frequent and secure flowline termination. Typical uses include capping off unused female ports on high-volume water transfer manifolds, isolating mud lines on drilling rigs, dead-ending production gathering systems, and securing temporary flowlines in general utility service.

Quality Assurance

Each blind sub is manufactured under strict quality control protocols. The component undergoes precise dimensional inspection—particularly of the critical O-ring groove and load-bearing shoulder—to ensure absolute interchangeability with standard 4" Fig 206 hammer unions and reliable blowout-proof performance under rated field pressures.
