3" 2,000 PSI Fig 206 Male Blind Sub with Wing Nut – Oil & Gas Hammer Union
Impossible de charger la disponibilité du service de retrait
The 3" Figure 206 Male Blind Sub with Wing Nut is a robust, medium-pressure closure assembly 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, the Figure 206 series is specialized for air, water, oil, or gas service where a dependable, leak-proof seal is required.
Manufactured from high-strength forged steel, this complete assembly includes the precision-machined male blind sub and the heavy-duty Figure 206 wing nut. A defining characteristic of the Figure 206 design is the inclusion of an O-ring groove on the male sub, which provides a secondary sealing mechanism. This ensures a bubble-tight seal even in applications subject to vibration or minor piping misalignment. Because it arrives pre-assembled with the wing nut, rig personnel can quickly deploy the blind to terminate 3-inch flowlines and manifolds using standard hammer-up techniques.
Built to withstand the rigors of field use, the 3" 206 Male Blind Sub with Wing Nut provides a safe, blowout-proof termination point for utility lines, water transfer systems, and production gathering manifolds.
